Explain Magnetostriction.
Magnetostriction: If ferromagnetic materials are magnetized a small change of dimensions of the material obtains place. There is a small extension along with equivalent reduction of cross-section of the crystals of that the material is made. When this rapidly alternating magnetic fields so there is a rapid and continuous extension and contraction of the material. It is termed as magnetostriction. This magnetostriction is the main cause of hum in transformers and chokes.
Q. Sketch the idealized (asymptotic) Bode plot for the transfer function Find the angular frequency at which H(ω) is 0dB and the angular frequency at which θ(ω) = -60°.
Explain the difference between a microprocessor and an embedded microcontroller
Two pure sine waves have similar amplitude "A" and frequency "f." They are out of phase through 180 degrees. If these two signals are added, the resulting waveform will be:
RMS of generator
Signals in Noise: Let us now consider a weak information signal that is to be amplified by a noisy amplifier. The signal-to-noise ratio (SNR), usually expressed in decibels, be
A 3 phase 400 volt(line to line) wye connected synchronous motor has Xs= 1 ohm per phase and a negligible armature resistance. The field current is so adjusted that the internal(in
Q. Can you explain twos Complement Division? 2's complement division is repeated 2's complement subtraction. The 2's complement of the divisor is calculated, and then added to
One of the simplest circuits is the asynchronous or ' ripple' counter. Below is shown the circuit diagram of a simple 3 stage ripple counter. The operation of this circuit
Explain working of Phase Shift Oscillator? Figure shows a phase shift oscillator. Here the combination of ReCe provides self bias for the amplifier. The phase of the signa
