Q1. What is modulation?
Ans. 
Modulation is the process of varying a carrier signal's properties to encode information for transmission.
• Modulation can change amplitude, frequency, or phase of the carrier signal.

• Amplitude Modulation (AM) is used in AM radio broadcasting.

• Frequency Modulation (FM) is commonly used in FM radio and television.

• Phase Shift Keying (PSK) is used in digital communication systems.

Q2. What is frequency?
Ans. 
Frequency is the number of occurrences of a repeating event per unit time, typically measured in Hertz (Hz).
• Frequency is measured in Hertz (Hz), where 1 Hz equals one cycle per second.

• In electronics, frequency determines the behavior of circuits, such as in oscillators and filters.

• Examples include audio frequencies (20 Hz to 20 kHz) for sound and radio frequencies (kHz to GHz) for communication.

• Higher frequencies can l...read more
