Question: Which modulation technique is used to transmit digital data over an analog channel?

Options:

Correct Answer: PSK

Solution:

Phase Shift Keying (PSK) is a modulation technique used to transmit digital data over an analog channel.

Which modulation technique is used to transmit digital data over an analog channel?

Which modulation technique is used to transmit digital data over an analog channel?

Step 1: Understand that digital data is information represented in binary form (0s and 1s).
Step 2: Recognize that an analog channel is a medium that can carry signals continuously, like radio waves.
Step 3: Learn that modulation is the process of varying a carrier signal to transmit data.
Step 4: Identify that Phase Shift Keying (PSK) is a specific type of modulation technique.
Step 5: Realize that PSK changes the phase of the carrier signal to represent different binary values.
Step 6: Conclude that PSK is used to effectively transmit digital data over an analog channel.
