Discuss differential protection, modified differential protection and percentage differential protection of alternators. Draw the suitable connection diagrams for clear understanding.
Determine the output voltage of an op-amp for input voltages of Vi1=200uV at Vi2=140uV. The amplifier has a differential gain of Ad=6000 and the value of CMRR is A. 200 b. 10^5
A buck converter has input voltage of 10 V, switching frequency 1 kHz, The load resistance of 5 Ω requires average voltage of 5 V with a maximum ripple of 20 mV. The maximum ripple current of the inductor is 0.2 A.
For a 128-PSK modulator with an input data rate equal to 56 Mbps and a carrier frequency of 100 MHz, determine (a) minimum required bandwidth and (b) baud rate.
Determine the N-point DFT X[n] of the N-point sequence x[n]=sin(ωon), 0≤n≤N-1, for ωo ≠ 2∏r/N, where r is an integer in the range 0
A 600 V, dc shunt motor has armature and field resistance of 15 ohms and 600 ohms respectively. When the motor runs unloaded, the ine current is 3 A, and the speed is 1000rpm. Calculate the developed torque at a full load armature current of 50 A.
