1.	A nyquist pulse is the one which can be represented by _____ shaped pulse multiplied by another time function.(a) Sine(b) Cosine(c) Sinc(d) None of the mentionedThe question was asked in a job interview.My question is taken from Intersymbol Interference-1 topic in portion Baseband Demodulation and Detection of Digital Communications
Answer» Right option is (c) Sinc For EXPLANATION I would say: A nyquist FILTER is one whose frequency transfer FUNCTION can be represented by a rectangular function convolved with any real EVEN symmetric frequency function and a nyquist pulse is one whose shape can be represented by sinc function multiplied by another time function.
