Signals

Signals are the fundamental building blocks of communication systems. They are used to represent information in a form that can be transmitted and received over a communication channel.

What are Signals?

Signals can be analog or digital. Analog signals are continuous waveforms that vary in amplitude, frequency, or phase to represent information. Digital signals are discrete-time waveforms that represent information using a finite set of values.

Why Study Signals?

Signals play a vital role in many fields, including:

• Communication systems: Signals are used to transmit information over communication channels such as telephone lines, coaxial cables, and fiber optic cables.
• Signal processing: Signals are processed to extract useful information, such as filtering out noise and extracting features.
• Control systems: Signals are used to control systems such as robots, aircraft, and industrial processes.
• Medical imaging: Signals are used to create images of the human body, such as X-rays, CT scans, and MRIs.
