Digital vs. Analog Signals

Front

What is an analog signal?

Back

An analog signal is a continuous signal that represents physical measurements. It can take any value within a given range.

Front

What is a digital signal?

Back

A digital signal is a discrete signal that represents data as a sequence of separate values, typically in binary form (0s and 1s).

Front

What is the main advantage of digital signals over analog signals?

Back

Digital signals are more reliable and can be easily stored and transmitted without degradation.

Front

How do analog signals represent information?

Back

Analog signals represent information through continuous variations in amplitude or frequency.

Front

How do digital signals represent information?

Back

Digital signals represent information using discrete values, typically in binary code.

Front

What is signal degradation?

Back

Signal degradation refers to the loss of quality in a signal as it travels over distance or through a medium.

Front

Why are digital signals considered more reliable than analog signals?

Back

Digital signals are less susceptible to noise and interference, making them more reliable for data transmission.
