Question

HELP!!

Answer 1

Answer: Changing the voltage or current in a circuit creates an analog signal.

Explanation:

We know that,

An analog signal uses to transfer of the messages one station to other station. An analog signal uses to convey the signal information.

The voltage ,current and frequency represent the information in the electronic signal.

So, Changing the voltage or current in a circuit creates an analog signal and a capacitor, a transistor and a resistor is the electronic device.

Answer 2

Most likely analog signal.
a capacitor, transistor and resistor are only devices used in an electrical circuit. Chaging current or voltage doesn't create devices out of thin air.
