Power spectral density of thermal noise remains uniform upto frequency ___________(a) 10^15 HZ(b) 10^5 HZ(c) 10^2 HZ(d) 10^13 HZI had been asked this question in an internship interview.This key question is from Carrier Acquistion Techniques in DSB-SC topic in chapter Double Sideband Suppressed Carrier Modulation of Analog Communications

Answer»

The correct ANSWER is (d) 10^13 HZ

Explanation: Power Spectral Density is the quantity of power PRESENT in a signal in the frequency domain. Power spectral density of thermal or white noise gets affected when the frequency becomes greater than 10^13 Hz and THUS, it remains uniform UPTO 10^13 Hz.
