Analog Signal
Analog signal explained in an easy to understand way:
Think about trying to adjust the water temperature in your shower to find that perfect balance between too hot and too cold. Just like the gradual change in water temperature as you turn the knob, an analog signal varies smoothly in its properties, such as amplitude and frequency. The continuous adjustment of the shower temperature parallels how an analog signal flows seamlessly, without abrupt changes, ensuring a fluid transition much like the smooth shift in a signal's wave pattern.

Analog Signal: A continuous signal whose properties, like amplitude and frequency, vary smoothly analog signal. Analog signals are smooth and continuous waves used to represent information, unlike digital signals, which use discrete onoff pulses.
