What is the difference between an analog signal and alternating current?

Click For Summary
SUMMARY

The discussion clarifies that an alternating current (AC) is a specific type of analog signal. An analog signal can represent a continuous range of values, while AC specifically alternates between two extreme values of opposite signs. The mathematical representation of an analog signal is exemplified by the equation i(t) = I sin(2πt), which illustrates its continuous nature. Thus, all alternating currents are analog signals, but not all analog signals are alternating currents.

An alternating current is an analogue signal.

An analogue signal is a signal which can take a whole range of values within a certain range.

For example, i(t) = I sin(2pit) takes all the values between -I and I so it's analogue.

An alternating current is a current which alternates between two values ( two extremes ), which are of opposite sign.

i(t) is also an alternating signal.
