8.PS4.3 Vocab - Signal Processing Concepts and Terminology

Front

What is a digital signal?

Back

A digital signal represents data as a series of discrete values, often in the form of 0s and 1s.

Front

What does reliability mean in signal processing?

Back

Reliability is the ability of a system to consistently perform its intended function.

Front

What is distortion in the context of signals?

Back

Distortion is the alteration of the original shape or other characteristics of a signal.

Front

What is an analog signal?

Back

An analog signal is a continuous signal that varies in amplitude or frequency.

Front

What is a wave pulse?

Back

A wave pulse is a single disturbance that moves through a medium from one point to another.

Front

What is attenuation in signal processing?

Back

Attenuation refers to the reduction in strength of a signal as it travels through a medium.

Front

What is modulation?

Back

Modulation is the process of varying one or more properties of a periodic waveform to encode information.

Front

What is the difference between analog and digital signals?

Back

Analog signals are continuous and can take any value, while digital signals are discrete and represent data in binary form.

Front

What is noise in signal processing?

Back

Noise refers to unwanted disturbances superimposed on a useful signal that can obscure or distort the information.

Front

What is sampling in digital signal processing?

Back

Sampling is the process of converting a continuous signal into a discrete signal by taking measurements at regular intervals.
