Q3. In a three-phase full-bridge inverter circuit, the de voltageV = 250V, the amplitude modulation indexma = 0.8, the frequency modulation index m, = 21, and the frequency of the three-phase sine modulating wave is 50 Hz. The load is a three-phase Y-connected RL load with R-592 and L=40mh. Calculate (a) the switching frequency, (b) the rms value of the output voltage and phase current at the fundamental frequency (c) the rms value of the dominant harmonics (consider only four components). [fr] s If the amplitude of the sin modulating wave is increased to 3.5 times the carrier frequency amplitude and load is changed to resistive load with R=52, (d) draw the line to neutral voltage (e) draw the line to line voltage (e) express the line to line voltage Vab by the Fourier series (consider the four dominant harmonic order only) (f) determine the active power consumed on three-phase load. chort-cirassis 1800

c) Draw a block diagram of a typical digital communications system including both transmit and receive paths and describe the nature of the signals generated by each of the blocks. Briefly describe what happens within the Modulator element and explain what is meant by the term 'up-conversion'.
