Analog Signals

At the heart of the modern technological landscape, analog signals play a pivotal role in bridging the gap between the physical and digital realms. From the subtle vibrations of a guitar string to the complex data streams transmitted through communication networks, analog signals carry vital information that shapes our everyday experiences.

Understanding Analog Signals

An analog signal is a continuous electrical waveform that varies its amplitude, frequency, or phase to represent information. Unlike digital signals, which are discrete and consist of a series of distinct values, analog signals exhibit a smooth, continuous flow of data.
