Q1:

Which of the following best defines Nyquist frequency?

A The frequency of resonance for the filtering circuit

B The second harmonic

C The lower frequency limit of sampling

D The highest frequency component of a given analog signal

ANS:D - The highest frequency component of a given analog signal

Nyquist frequency is twice the max. Frequency of an analog signal which eliminate aliasing effect.
