Question

Which of the following statements is TRUE in regards to Signal #2?

1) Signal #2 is a digital signal that transmits signals continuously.


2) Signal #2 is a digital signal that transmits signals in segments/intervals.


3) Signal #2 is an analog signal that transmits signals continuously.


4) Signal #2 is an analog signal that transmits signals in segments/intervals.

Answer 1

2) Signal #2 is a digital signal that transmits signals in segments/intervals.

Step-by-step explanation:

Signals are form of information propagating from the source to a display unit for appropriate interpretation. It can be either in a digital or analogue form.

A digital signal is a definite signal which is discrete in time and amplitude. It is mostly in the form of codes obtained from set of values. Graphically it transmits in the form of 1 and 0, showing a point of maximum amplitude (1) and minimum amplitude (0).

Analog signal is continuous signal describing the variation of two variables with respect to time.
