FAQs on Angle Modulation, Communications, Electrical Engineering, GATE Video Lecture - Electronics and Communication Engineering (ECE)
| 1. What is angle modulation in communications? |  |
Ans. Angle modulation is a technique used in communications to encode information onto a carrier wave by varying the phase or frequency of the wave. It includes two main types: frequency modulation (FM) and phase modulation (PM). In FM, the frequency of the carrier wave is modulated, while in PM, the phase of the carrier wave is modulated.
| 2. How is frequency modulation (FM) different from phase modulation (PM)? | |
Ans. FM and PM are two different types of angle modulation. In FM, the frequency of the carrier wave is varied according to the input signal, while in PM, the phase of the carrier wave is varied. FM provides a constant amplitude of the carrier wave, while PM can cause amplitude variations. FM is more commonly used in broadcast radio, while PM is used in applications such as digital communication.
| 3. What are the advantages of angle modulation in communication systems? | |
Ans. Angle modulation offers several advantages in communication systems. Firstly, it provides better noise immunity compared to amplitude modulation (AM) as it is less affected by amplitude variations. Secondly, it allows for a larger number of channels to be transmitted within a given frequency band. Additionally, angle modulation techniques have better sound quality in audio applications and provide better resistance to multipath interference.
| 4. How does angle modulation affect the bandwidth of a signal? | |
Ans. Angle modulation techniques, such as FM and PM, require a larger bandwidth compared to amplitude modulation. The bandwidth of an angle-modulated signal depends on the modulation index, which is the ratio of the frequency deviation or phase deviation to the frequency of the input signal. Higher modulation index values result in larger bandwidth requirements. Therefore, for a given input signal, angle modulation requires a wider bandwidth compared to amplitude modulation.
| 5. How is angle modulation used in practical applications? | |
Ans. Angle modulation techniques, especially FM, are widely used in practical applications. FM is commonly used in broadcast radio, where it provides high-quality audio transmission with good noise immunity. It is also used in wireless communication systems, such as mobile phones, to transmit voice and data signals. PM is used in digital communication systems, such as phase-shift keying (PSK) modulation, where the phase of the carrier wave is modulated to transmit digital information.
