the paper fabricates an analog probability decoder of trellis code by using CMOS analog circuits. The decoding performance is given. When the SNR is over 4.8dB, for 950KHz input signal, the analog ...

The 74AHC138 and 74AHCT138 are high-speed Si-gate CMOS devices and are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC138 and ...

On one end of the twisted pair is a power supply and decoder circuit, which sends 9 volts up the line to power the PIC sensor. The decoder is based on a CD4538 dual monostable multivibrator ...
