Question

The transformation of the waveform into a single point in signal space is called as

(a) Vector point

(b) Predetection point

(c) Preamplification point

(d) Transformation point

I got this question in a job interview.

The above asked question is from Digital Bandpass Modulation Techniques topic in division Bandpass Modulation and Detection of Digital Communications

Answer 1

Right answer is (b) Predetection point

Easy explanation: The first step of the detection process is to reduce waveform into a single or group of random variable. This first step in the transformation of waveform into a point in signal space. This point is called as predetection point.
