Question

how do analog signals create a continuous flow of information?
by stopping and starting in a specific pattern.
by sending information in separate, individual packets.
by constantly changing its frequency.
by using a single, unchanging wave pulse.

Explanation:

Analog signals are defined by continuous, variable physical properties (like frequency, amplitude) that change smoothly over time to carry information. The other options describe digital signal behavior (packetized, on/off patterns, fixed pulses).

Answer:

C. By constantly changing its frequency.
