A continuous-phase FSK signal with h = 1/2 is represented as
where the ± signs depend on the information bits transmitted.
1. Show that this signal has a constant amplitude.
2. Sketch a block diagram of the modulator for synthesizing the signal.
3. Sketch a block diagram of the demodulator and detector for recovering the information.
what effect does the diode barrier potential have on the difference between the peak input voltage and the peak output voltage Explain
A three-phase generator rated 480 V, 400 kVA is connected to a three-phase transformer rated 3.2 kV Y-grounded/480 V, 200 kVA, with reactance of 10%. The transformer is 100% loaded based on its rating at 0.9 pf leading.
Suppose a resistor whose value is equal to the motor resistance is connected across the motor terminals and the motor is spun at 200 RPMs. What will be the voltage measured across the motor terminals
