1) Describe in detail about the indirect method of generation of FM wave and method of demodulating an FM wave.
2) Deduce an expression for frequency modulated signal. Describe what do you mean by narrowband FM and wideband FM by using an expression?
3) Describe the techniques of demodulation of FM in detail.
4) Describe the working of reactance tube modulator in detail and deduce the expression to illustrate how variation of amplitude of input signal varies the frequency of the output signal of the modulator.
5) Design the frequency spectrum of FM and describe. Describe how Varactor diode can be used for frequency modulation.
6) describe the indirect method of generating the wide-band FM signal.
7) Design the circuit diagram of Foster-Seelay discriminator and describe it’s working in detail.
8) Describe a random variable. State the sample space and random variable for a coin tossing experiment.
9) What do you mean by white noise? prepare down its characteristics.
10) Describe when a random process is known as deterministic?
