In digital modulation, an analog carrier signal is modulated by a discrete signal. Digital modulation methods can be considered as digital-to-analog conversion and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols (the modulation alphabet). WebLab 1: Amplitude Modulator and Demodulator Objective. To understand the theoretical foundations of Analog Communications as well as of Double-Side-Band Amplitude Modulation and Demodulation (DSB-AM) To design the Simulink model of the DSB-AM to analyze each signal in time and frequency domains using time scope and spectrum analyzer WebSOO modulation realizes accurate regulation over wide load/VIN range while maintaining high efficiency and low output ripple. The switching frequency in the PWM mode is 500 kHz.
