Question

If each element of signal occupies 70ms, what will its speed?

(a) 11.23 bauds

(b) 14.28 bauds

(c) 17.39 bauds

(d) 13.33 bauds

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

This intriguing question comes from Power Calculation topic in section Amplitude Modulation of Analog Communications

Answer 1

Right choice is (b) 14.28 bauds

To elaborate: The carrier signal is characterized by the number of signal intervals, or pulses, that are transmitted per second. Each pulse is called a baud. Bps stands for bits per second. Bps is a measure of how many bits can be transmitted during one pulse (one baud).
