problem 3: What do you mean by the transit time noise in a transistor?

problem 4: Define the term transistor signal-to-noise ratio and noise figure of a receiver.

problem 5: Define the term noise figure of a circuit. describe an experimental method of determination of the noise figure.

problem 6: Describe the types, causes and effects of the different forms of noise which might be cleared in a receiver or amplifier.

problem 7: List separately, the different sources of random noise and impulse noise and external noise. How can some of them be minimized or avoided.
