This is the GATE instrumentation engineering Last years question paper:

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
(A) 840 Hz to 1320 Hz (B) 960 Hz to 1200 Hz
(C) 1080 Hz to 1320 Hz (D) 720 Hz to 1440 Hz
