Question

In time-domain expression, \(x_+ (t)=F^{-1} [2V(F)]*F^{-1} [X(F)]\). The signal x+(t) is known as

(a) Systematic signal

(b) Analytic signal

(c) Pre-envelope of x(t)

(d) Both Analytic signal & Pre-envelope of x(t)

I had been asked this question in quiz.

The origin of the question is The Representation of Bandpass Signals topic in chapter Sampling and Reconstruction of Signals of Digital Signal Processing

Answer 1

Right answer is (d) Both Analytic signal & Pre-envelope of x(t)

To explain I would say: From the given expression, \(x_+ (t)=F^{-1} [2V(F)] * F^{-1}[X(F)]\).
