The video introduces the concept of news as LG and provides an overview of modulation circuits.

What is the primary purpose of modulation in communication systems?

• To improve the sound quality of the signal

• To allow the transmission of signals over long distances

• To increase the power of the signal

• To reduce the size of the antenna

Which component is essential in a modulation circuit?

• Inductor

• Modulator

• Capacitor

• Resistor

How does modulation affect the frequency of a signal?

• It decreases the frequency

• It increases the frequency

• It keeps the frequency constant

• It shifts the frequency to a different range

What is a common application of modulation circuits?

• Signal amplification

• Radio broadcasting

• Power supply regulation

• Data storage

Which of the following is NOT a type of modulation?
