The limiter recovers quickly from brief transients, so that its action is hidden from the listener, but recovers slowly from sustained high levels to keep audio distortion low and preserve short term dynamic changes in the audio level.

Clelanda) Department of Physics and iQUEST, University of California, Santa Barbara, Santa Barbara, California 93106 ͑Received 14 March 2002; accepted for publication 10 May 2002͒ We demonstrate the use of the single-electron transistor as a radio-frequency mixer, based on the nonlinear dependence of current on gate charge. This mixer can be used for high-frequency, ultrasensitive charge measurements over a broad and tunable range of frequencies. We demonstrate operation of the mixer, using a lithographically defined thin-film aluminum transistor, in both the superconducting and normal states of aluminum, over frequencies from 10 to 300 MHz. We have operated the device both as a homodyne detector and as a phase-sensitive heterodyne mixer. We demonstrate a charge sensitivity of Ͻ4ϫ10Ϫ3 e/ͱHz, limited by room-temperature electronics. An optimized mixer has a theoretical charge sensitivity of Շ1.5ϫ10Ϫ5 e/ͱHz. © 2002 American Institute of Physics. ͓DOI: 10.1063/1.1493221͔ Coulomb blockade can occur when current through a linear dependence of the current I on the coupled charge is device passes through high-resistance contacts to a small- employed to mix a rf signal to dc, while in the latter, the capacitance island.

Polytechnic Manesar 1 CHAPTER-1 AM/FM TRANSMITTERS Learning Objectives: After the completion of this chapter, the students will be able to: Classify the transmitters on the basis of modulation, service, frequency and power Demonstrate the working of each stage of AM and FM transmitters 1.1 Classification of Radio Transmitters 1.1.1 Classification on the basis of type of modulation used 1. Amplitude Modulation Transmitters: Here the modulating signal modulates the carrier with respect to its amplitude. AM transmitters are used for radio broadcast, radio telephony, radio telegraphy and TV picture broadcast. 2. Frequency Modulation Transmitters: In FM transmitters, the frequency of the carrier is varied in accordance with the modulating signal. These are used for radio broadcast, TV sound broadcast and radio telephone communication. 3. Pulse Modulation Transmitters: The signal changes any of the characteristics like pulse width, position, amplitude of the pulse carrier. 1.1.2 Classification on the basis of the service involved 1. Radio Broadcast transmitters: These transmitters are particularly designed for broadcasting speech signals, music, information etc. These systems may be amplitude or frequency modulated. 2. Radio Telephone Transmitters: These transmitters are mainly used for transmitting telephone signals over long distance by radio waves. The transmitter uses volume compressors, peak limiters etc. 3. Radio Telegraph Transmitters: It transmits telegraph signals from one radio station to another radio station. The transmitter uses either amplitude modulation or frequency modulation. 4. Television Transmitters: TV broadcast requires transmitters for transmission of picture and sound separately.

  • Flow Patterns and Energy Dissipation Rates in Batch Rotor-Stator Mixers

ABSTRACT The flow pattern and distribution of energy dissipation rate in a batch rotor-stator mixer fitted with disintegrating head have been numerically investigated. Standard k-ε turbulence model in conjunction with sliding mesh method was employed and the simulation results were verified by laser Doppler anemometry (LDA) measurements. The agreement between predicted and measured velocity profiles in the bulk and of jet emerging from stator hole was very good. Results showed that the interaction between stator and rotating blades generated periodic fluctuations of jet velocity, flowrate, torque and energy dissipation rate around the holes. The kinetic energy balance based on measured velocity distribution indicated that about 70% of energy supplied by the rotor was dissipated in close proximity to the mixing head, while the simulation predicted that about 60% of energy dissipated in the same control volume.

Prototype cavity BPM pick-up was designed and fabricated to test performance of cavity BPM system. Fabricated prototype cavity BPM pick- up was installed at the beam line of Injector Test Facility (ITF) at PAL for beam test. Under 200 pC beam charge condition, the signal properties of cavity BPM pick-up were measured. Also, the dynamic range of cavity BPM was measured by using the corrector magnet. In this paper, the design and beam test results of prototype cavity BPM pick-up will be introduced. PAL-XFEL Cavity Beam Position Monitor Fabricated Prototype PAL-XFEL CBPM PAL-XFEL will provide X-rays in ranges of 0.1 to 0.06 nm for hard X-ray line and 3.0 nm to 1.0 nm for soft X-ray line by using the self-amplified spontaneous emission (SASE) Schematic [1, 2, 3]. To generate X-ray FEL radiation, the PAL-XFEL undulator section requires high resolution beam position monitoring systems with <1 μm resolution for single bunch. To achieve high resolution requirement, the PAL-XFEL undulator section will use the cavity BPM. Total 49 units of cavity BPM system will be installed in between each undulators with other diagnostics tools.
