Signal from fifteen thermocople are multplexed and each one is sampled once per second with 16 bit ADC. The digital sample are converted by a parallel to serial converter to generate a serial PCM signal.this pcm signal is frequncy modulated with FSK modulator with 1200 hz as 1 and 960 hz as 0.the min band allocation requrired for faithful reproduction of the signal by FSK Receiver without considering noise is a)840Hz to1350 Hz b)960Hz to1200 Hz c)1080Hz to1320 Hz d)720Hz to1440 Hz
