Question

Analog signals : Signal to noise ratio:: Digital signals  _________

(a) Signal Attenuation

(b) Bit error rate

(c) Error rate

(d) Digital noise ratio

I have been asked this question by my college professor while I was bunking the class.

My question is taken from Communication Receivers topic in section Radio Transmitters, Communication Receivers, Multiplexing and Demultiplexing of Avionics

Answer 1

The correct option is (b) Bit error rate

The explanation is: For analog signals, the signal-to-noise ratio is the main consideration in analog signals. For digital signal transmission, the bit error rate (BER) is the main consideration. BER is the number of errors made in the transmission of many serial data bits.
