  • Reception Performance Improvement of AM/FM Tuner by Digital Signal Processing Technology
    Reception performance improvement of AM/FM tuner by digital signal processing technology Akira Hatakeyama Osamu Keishima Kiyotaka Nakagawa Yoshiaki Inoue Takehiro Sakai Hirokazu Matsunaga Abstract With developments in digital technology, CDs, MDs, DVDs, HDDs and digital media have become the mainstream of car AV products. In terms of broadcasting media, various types of digital broadcasting have begun in countries all over the world. Thus, there is a demand for smaller and thinner products, in order to enhance radio performance and to achieve consolidation with the above-mentioned digital media in limited space. Due to these circumstances, we are attaining such performance enhancement through digital signal processing for AM/FM IF and beyond, and both tuner miniaturization and lighter products have been realized. The digital signal processing tuner which we will introduce was developed with Freescale Semiconductor, Inc. for the 2005 line model. In this paper, we explain regarding the function outline, characteristics, and main tech- nology involved. 22 Reception performance improvement of AM/FM tuner by digital signal processing technology Introduction1.

  • ELEC3027 Radio Communications Background Information on Amplitude Modulation
    ELEC3027 Radio Communications Background Information on Amplitude Modulation 1 Analogue Modulation 1.1 Amplitude Modulation When a Radio Frequency (RF) signal is placed onto the antenna of a transmitter, it will propagate through free space and can be detected on the antenna of a receiver. The higher the frequency of this signal, the smaller the antennas that are required. However, we are often interested in communicating relatively low frequency message signals, such as audio. Hence, we must modulate our low frequency message signal onto a high frequency carrier, in order to transmit it. This has the added benefit of allowing us to modulate different message signals onto different carrier frequencies, in order to transmit them without interfering with each other. Figure 1 shows the schematic of a transmission scheme that uses Amplitude Modulation (AM) to transmit a time-varying input signal x(t), as well as demodulation to obtain a received signal xˆ(t). Modulator Demodulator A cos(2πfct) x(t) y(t) u(t) xˆ(t) + LPF × Figure 1: AM modulation and demodulation. 1.1.1 Operation The AM modulator of Figure 1 uses the message signal x(t) to vary the amplitude of the carrier sinusoid cos(2πfct), where the carrier frequency fc is usually much higher than the highest frequency in the message signal. As shown in Figure 1 y(t) = [A + x(t)] cos(2πfct), (1) 1 where A is a constant DC offset. In the AM demodulator of Figure 1, the diode symbol represents a rectifier which gives y(t) if y(t) > 0 u(t)= .

    Modulation and Signal Generation with R&S® Signal Generators Educational Note Products: ® ı R&S SMB100A ® ı R&S SMBV100A ® ı R&S SMC ı HM8134-3/HM8135 ı HMF2525 / HMF2550 Signal generators play a vital role in electrical test and measurement. They generate the test signals that are applied to components such as filters and amplifier, or even to entire modules, in order to ascertain and test their behavior and characteristics. The first part of this educational note presents the applications for and the most important types of signal generators. This is followed by a description of the construction and functioning of analog and vector signal generators. To permit a better understanding of the specifications found on data sheets, a closer look at the most important parameters for a signal generator is provided. Beyond the output of spectrally pure signals, a key function of RF signal generators is the generation of analog- and digitally modulated signals. The second part of this note therefore presents the fundamentals for the most significant analog and digital modulation methods. The third part of this educational note contains exercises on the topics of analog and digital modulation. All described measurements were performed using the R&S®SMBV100A vector signal generator and the R&S®FSV spectrum analyzer.

  • Double Sideband (DSB) and Amplitude Modulation (AM)
    Double Sideband (DSB) and Amplitude Modulation (AM) Modules: Audio Oscillator, Wideband True RMS Meter, Multiplier, Adder, Utilities, Phase Shifter, Tuneable LPF, Quadrature Utilities, Noise Generator, Speech, Headphones 0 Pre-Laboratory Reading Double sideband (DSB) is one of the easiest modulation techniques to understand, so it is a good starting point for the study of modulation. A type of DSB, called binary phase-shift keying, is used for digital telemetry. Amplitude modulation (AM) is similar to DSB but has the advantage of permitting a simpler demodulator, the envelope detector. AM is used for broadcast radio, aviation radio, citizens’ band (CB) radio, and short-wave broadcasting. 0.1 Double Sideband (DSB) Modulation A message signal 푥(푡) can be DSB modulated onto a carrier with a simple multiplication. The modulated carrier 푦(푡) can be represented by 푦(푡) = 푥(푡) ∙ cos⁡(2휋푓푐푡) (1) where 푓푐 is the carrier frequency. The Fourier transform 푌(푓) of the modulator output is related to the Fourier transform 푋(푓) of the message signal by 1 1 푌(푓) = 푋(푓 − 푓 ) + 푋(푓 + 푓 ) 2 푐 2 푐 (2) For a real 푥(푡), |푋(푓)| is symmetric about 푓 = 0 and |푋(푓 − 푓푐)| is symmetric about 푓 = 푓푐. For the present discussion, it is only necessary to consider that part of 푌(푓) that lies in the positive half of the frequency axis. The signal content that lies in the frequency domain below 푓푐 is the lower sideband. The signal content that lies in the frequency domain above 푓푐 is the upper sideband.

    April 27, 2017 FCC FACT SHEET* Part 95 Personal Radio Service Reform Report and Order - WT Docket No. 10-119 Background: The Commission’s Part 95 Personal Radio Services (PRS) rules address a wide variety of wireless devices that are used by the general public to satisfy personal communications needs. These devices generally use low-power transmitters, communicate over shared radio frequencies, and (with a few exceptions) do not require an individual FCC license for each user. Some common examples of PRS devices include walkie-talkies; radio control toy cars, boats, and planes; hearing assistance devices; CB radios; medical implant devices; and Personal Locator Beacons. This draft Report and Order completes a thorough review of the PRS rules in order to modernize them, remove outdated requirements, and reorganize them to make it easier to find information. As a result of this effort, the rules will become consistent, clear, and concise. What the Rules Would Do: GMRS/FRS Reform. General Mobile Radio Service (GMRS) and Family Radio Service (FRS) devices are both used for personal communications over several miles. The public may be most familiar with FRS walkie-talkies. While GMRS and FRS share spectrum, GMRS provides for greater communications range and requires an FCC license, while FRS does not require a license. The rules will increase the number of communications channels for both GMRS and FRS, expand digital capabilities to GMRS (currently allowed for FRS), and increase the power/range for certain FRS channels to meet consumer demands for longer range communications (while maintaining higher power capabilities for licensed GMRS).
