  • Difference Between GSM, GPRS, EDGE, 3G, WCDMA, HSDPA and 4G
    Difference between GSM, GPRS, EDGE, 3G, WCDMA, HSDPA and 4G It's a very basic and non-technical comparison. GSM GSM, stands for Global Systems for Mobile Communications, is basic standard bearer of 2G technologies. It is mainly used in mobile communication. Short Messaging System (SMS) was introduced into GSM networks along with capability to download content from various service providers. The content could ring tone, logos and picture messages. It can support Voice telephony and data however the data rate is only 9.6Kb/s, that is very low bit rate for date communication. GPRS GPRS, stands for General Packet Radio Service, is used to give higher data speed over GSM. It is not the replacement of GSM. It is just an extension to the older GSM technology to gain faster speed. Multimedia Messaging System or MMS is the feature of GPRS. It allowed subscribers to send videos, pictures, or sound clips to each other just like text messages. GPRS also provided mobile handset the ability to surf the Internet at dial-up speeds through WAP enabled sites. GPRS offers higher bit rate (Up to 171kb/s) by usage of A packet-linked technology over GSM. EDGE EDGE stands for Enhanced Data Rates for GSM Evolution. This technology, also termed as Enhanced GPRS. This is a technology that uses the same equipment as GSM with only a few minor modifications to provide faster data speeds and is often regarded as a stepping stone towards 3G thus it is called 2.5G. EDGE gives the users the inimitable chance to increase the throughput capacity and the data speed at least 3 to 4 times higher to what GPRS offers.

Industry experts stress how quickly the change is coming. Within the next five years, “more users will connect to the Internet over mobile devices than desktop PCs.” “By 2014,” according to Gartner, “90 percent of organizations will support corporate applications on personal devices.” Government in a In the current mobile landscape over 1 billion people already own mobile devices.

  • MC14SM5567 PCM Codec-Filter
    Product Preview Freescale Semiconductor, Inc. MC14SM5567/D Rev. 0, 4/2002 MC14SM5567 PCM Codec-Filter The MC14SM5567 is a per channel PCM Codec-Filter, designed to operate in both synchronous and asynchronous applications. This device 20 performs the voice digitization and reconstruction as well as the band 1 limiting and smoothing required for (A-Law) PCM systems. DW SUFFIX This device has an input operational amplifier whose output is the input SOG PACKAGE CASE 751D to the encoder section. The encoder section immediately low-pass filters the analog signal with an RC filter to eliminate very-high-frequency noise from being modulated down to the pass band by the switched capacitor filter. From the active R-C filter, the analog signal is converted to a differential signal. From this point, all analog signal processing is done differentially. This allows processing of an analog signal that is twice the amplitude allowed by a single-ended design, which reduces the significance of noise to both the inverted and non-inverted signal paths. Another advantage of this differential design is that noise injected via the power supplies is a common mode signal that is cancelled when the inverted and non-inverted signals are recombined. This dramatically improves the power supply rejection ratio. After the differential converter, a differential switched capacitor filter band passes the analog signal from 200 Hz to 3400 Hz before the signal is digitized by the differential compressing A/D converter. The decoder accepts PCM data and expands it using a differential D/A converter. The output of the D/A is low-pass filtered at 3400 Hz and sinX/X compensated by a differential switched capacitor filter.
