1.	Audio frequency range lies between _________(a) 2 MHz to 20 MHz(b) 20 Hz to 20 KHz(c) 20 KHz to 200 KHz(d) 20 MHz to 200 MHzThis question was posed to me by my school principal while I was bunking the class.Origin of the question is Pre Emphasis and De Emphasis in section Receivers & Transducers of Analog Communications
Answer» The correct answer is (b) 20 Hz to 20 KHz The BEST I can explain: As per standards audio frequency range lies in between 20 Hz to 20 KHz. This is the human audible range.
