Consider a three-phase induction motor with a normal torque-speed characteristic. Neglecting the effects of stator resistance and leakage reactance, discuss the approximate effect on the characteristic, if:
(a) The applied voltage and frequency are halved.
(b) Only the applied voltage is halved, but the frequency is at its normal value.
Peak inverse Voltage Peak inverse voltage is important parameter in the design of rectifier circuit. PIV is the maximum voltage that appears across the device during its
Define Hysteresis Hysteresis is the 'lagging' effect of flux density B whenever there are changes in the magnetic field strength H. When an initially unmagnetized ferromagnetic
Q. Let m 1 (t) and m 2 (t) be two message signals, and let u 1 (t) and u 2 (t) be the corresponding modulated versions. (a) When the combined message signal m 1 (t) + m 2 (t) DS
Estimate the software tasks required for developing the product. These are likely to include the development of various software routines, associated documentation and verification
Q. Describe Common-Mode Rejection Ratio ? When there is a common-mode input voltage, i.e., when the input signals are equal and greater than zero, the output voltage of an idea
Mechanical Structure of Depletion Type MOSFET The mechanical structure of this type of device is displayed in figure. In an IC, we would locate two n-type regions side by side

1. Find the Nyquist rate for the following signals: (a) x(t) = 5 sin 3000Πt cos 4000Πt (b) A binary channel with bit rate 36000 bps is available for PCM voice transmission.
can you please briefly explain about significance of the word direction in vectors with some valid points
Q. Several forms of interference? Interference may take several forms: ac hum, higher frequency pulses and "whistles," or erratic waveforms commonly known as static. Interferin
