When the modulation index is expressed as a percentage, it is commonly referred to as the "percentage modulation." This representation indicates the extent of modulation in relation to the carrier signal, showing how much the amplitude of the carrier varies due to the modulating signal. It provides a clearer understanding of modulation depth for practical applications in communication systems.
Pulse position modulation offers high noise immunity, efficient use of bandwidth, and easy implementation with digital circuits. This modulation technique is particularly useful in applications requiring high data transmission rates and reliable communication in noisy environments.
Delta modulation is extremely important for high-tech lives that humans live today. Delta modulation is basically analog to digital and digital to analog signal providers, allowing for radio communication devices such as TV remotes.
PWM finds use in power applications like dc motor speed control
Its used in collector amplitude modulation,Radio frequency recievers ..etc
Amplitude Modulation Double Sideband Full Carrier (AM DSB FC) is primarily used in analog broadcasting, such as AM radio stations, where it transmits audio signals over long distances. Additionally, it finds applications in two-way radio communications, aviation communication systems, and in some television broadcasts. Due to its simplicity and ease of demodulation, AM DSB FC is also used in various telemetry and remote sensing applications. However, it is less efficient in terms of bandwidth and power compared to modern modulation techniques.
