Question 1: Describe the term thermal noise.
Question 2: What do you mean by term short noise? Write down the expression for the short noise current in a diode.
Question 3: What do you mean by the transit time noise in a transistor?
Question 4: Define the term transistor signal-to-noise ratio and noise figure of a receiver.
Question 5: Define the term noise figure of a circuit. Explain an experimental method of determination of the noise figure.
Question 6: Describe the types, causes and effects of the different forms of noise which might be cleared in a receiver or amplifier.
Question 7: List separately, the different sources of random noise and impulse noise and external noise. How can some of them be minimized or avoided.
