Signals from fifteen thermocouples are multiplexed and each one is sampled once per second with a16–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

Data rate from ADC is 16 x 15 bits/second=240 bits/second
The bandwidth required for transmitting 240 bits/second = 120 Hz. (Half of bit rate).
Now when each pulse representing ‘1’s and ‘0’ s get FSK modulator with 960 Hz and 1200
Base band signal before modulation
The spectrum of signal after modulation
Thus all frequency from 840 to 1320 is required for allocation

-bit analog-to-digital converter (ADC). This means that the ADC can convert the analog voltage from each thermocouple into a digital value with a resolution of 16 bits.
Multiplexing is a technique used to share a single ADC across multiple input channels. In this case, the fifteen thermocouples are connected to the multiplexer, which sequentially selects each thermocouple and connects it to the ADC for conversion. This allows all fifteen thermocouples to be sampled using a single ADC.
The sampling rate is once per second, meaning that the ADC takes a measurement from each thermocouple every second. The resolution of the ADC is 16 bits, which determines the level of detail or precision in the digital representation of the analog voltage from each thermocouple.
Overall, this setup allows for the simultaneous sampling of multiple thermocouples with a reasonably high resolution, providing accurate measurements of temperature from each thermocouple.
