An H-bridge allows a 4 A current pulse to the drive motor. What is the average current if the duty cycle is 75% and the pulse frequency is 2 kHz
The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
RC ciruit= Current course (3u(-t) A) in parrallel to 6k ohm resistor and 5uF cap. Determine the instantaneous power absorbed by the resistor at t=(0); 30ms; and 90ms.
The resistance of the field circuit of a shunt-excited dc generator is 200. When the output power of the generator is 100kW, the terminal voltage is 500V and the generated e.m.f is 525V.
Water is flowing out of a tube at a near constant volumetric flowrate, V .If a graduated cylinder is used to collect a certain volume, v , of the water, and a timer is used to measure the time, t, required to collect the volume of water, the volum..
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss
What kind of transistor has higher voltage gain, BJT or FET and why What kind of transistor has better noise response BJT or FET and why How about frequency response high frequency, FET or BJT Low frequency response, FET or BJT
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
A 10 kHz signal modulates a 500 MHz carrier, with a modulation index of 2. What are the maximum and minimum values for the instantaneous frequency of the modulated signal
