1.	The rms value of a thermal noise voltage is proportional to (where k is Boltzmann’s constant) _______(a) √k(b) k(c) k^2(d) k^^1⁄3I have been asked this question in an online quiz.Question is taken from Quadrature Carrier Multiplexing topic in division Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» Correct answer is (a) √k The best I can explain: THERMAL noise is the noise generated in electronic DEVICES at frequencies below a few kilohertz, due to thermal EXCITATION of electrons. The root mean square value of thermal noise is proportional to root k TIMES, where k represents Boltzmann’s CONSTANT.
