What are the types of analog signal?
An Analog Signal is a continuous signal, just like an electric
current that flows through the copper cables when your electrical
appliances are turned on. This continuous signal represents
physical measurements. An example of this would be with an analog
audio signal, the voltage amount of the signal changes continuously
with the change in sound waves. Analog Signals are normally
represented as electrical signals, but there is also Classical
Mechanics, Pneumatics, and Hydraulics technique's that can be used
in analog signals.
