Question

Which of the following is false with respect to pulse modulation?

(a) Less power consumption

(b) Low noise

(c) Degraded signal can be regenerated

(d) Can transmit analog as well as digital waves

This question was posed to me in an interview for job.

My question comes from Pulse Modulation in division Digital Communication Techniques of Avionics

Answer 1

Right option is (d) Can transmit analog as well as digital waves

For explanation: Analog values cannot be transmitted as such by pulse modulation since it can only transmit binary data. However, the analog signal can be converted into digital using an ADC and then transmitted via pulse modulation.
