1.	What is Fidelity?(a) Equally amplifies all the signal frequencies at receiver(b) Ability of receiver to select wanted signal from various incoming signal(c) Minimum magnitude of input signal required to produced a specified output(d) Ability to amplify weak signalsI had been asked this question by my school teacher while I was bunking the class.My doubt is from Receiver topic in portion Elements of Communication System of Analog Communications
Answer» Right option is (a) Equally AMPLIFIES all the signal frequencies at receiver The EXPLANATION: Fidelity is the ability of the receiver to reproduce all modulating signals, equally, without any distortion. The ability of receiver to select wanted signal from various INCOMING signals is called Selectivity while Sensitivity is the minimum magnitude of input signal required to produce a specified output. It is the ability to AMPLIFY weak signals.
