Front

What is filtering in signal processing?

Back

A technique used to remove noise from a signal.

Front

What does modulation do in signal processing?

Back

It alters a carrier signal to encode information.

Front

What is multiplexing?

Back

A technique that combines multiple signals into one for transmission.

Front

What is demodulation?

Back

The process of extracting the original information from a modulated carrier wave.

Front

What is the time domain in signal processing?

Back

A representation of a signal as it varies over time.

Front

What is the frequency domain in signal processing?

Back

A representation of a signal in terms of its frequency components.
