Question
Signals from fifteen thermocouples are multiplexed and each one is sampled once per second with a
16-bit ADC. The digital samples are converted by a parallel to serial converter to generate a serial
PCM signal. This PCM signal is frequency modulated with FSK modulator with 1200 Hz as 1 and
960 Hz as 0. The minimum band allocation required for faithful reproduction of the signal by the
FSK receiver without considering noise is
