The spectrum of white noise and impulse noise is similar in terms of ________(a) magnitude spectrum(b) phase spectrum(c) both magnitude spectrum and phase spectrum(d) amplitude spectrumI have been asked this question at a job interview.The question is from Frequency Domain Representation in portion Double Sideband Suppressed Carrier Modulation of Analog Communications

Answer»

Right ANSWER is (a) MAGNITUDE spectrum

Easy explanation: White noise is a random signal having equal intensities of different frequencies. IMPULSE noise is a type of noise CONSISTING of sudden sounds, which includes unwanted and instantaneous signals. THUS, they have only their magnitude in common.
