What happens when clipping occurs in a inverting amplifier?
The output waveform will be limited to the difference between the supply and ground (or between the positive and negative supplies). This causes distortion of the output waveform.
How hartley oscillator produces a output waveform without input?
it uses the noise in air.
Another way of saying that the output is 70 percent of the signal input at cutoff frequency is that the output is up or down dB at frequency cutoff?
If the output power is 70% of the input power, then the output is roughly 1.55 dB downcompared to the input.If the voltage at any point of the output waveform is 70% of the voltage at the same pointon the input waveform, and the input and output impedance are equal, then the output is3.1 dB down (rounded) compared to the input.
Which harmonics is present in full bridge rectifire?
Since the output of the rectifier is a close approximation of a sawtooth waveform, then all harmonics starting at the second harmonic are present in the full wave bridge rectifier output.
How do you make power supply variable?
A variable power supply is one whose output voltage (or current) can be adjusted and therefore set to a desired figure. They are used in development and design odf circuits, eliminating the need for possibly many power supplies of different output voltages. Once a circuit is connected to it, the output would not normally be changed.

What are linear wave Shaping circuits?
if a sinusoidal voltage is applied to linear circuit the output voltage is also sinusoidal in nature as far as the waveform is concerned the amplitude of input signal may change and there may be phase displacement between input voltages and output voltages
Why use the capacitor in the full rectifier?
to smooth the output waveform
Find the output waveform of op amp when inverted input terminal connected to a ground and a sinusoidal signal of 4 v peak at non inverting input?
In this configuration the opamp basically works as a non inverting comparator. During the positive cycle of the waveform the output will saturate to positive Vcc, while during the negative cycle the output saturates to negative Vcc. Therefore the output waveform is a square wave with amplitude equal to the supplies and period equal to the input waveform.
What is the effect of the filter capacitor on the output wave shape of the rectifier?
The larger the cap the smaller the ripple at the power supplies output. It smooths the rectifiers output waveform.

What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
How the output characteristics of AC and DC generator vary from other?
AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.
How is a DC waveform produced from the output terminals of a DC generator?
A DC waveform is produced from the output terminals of a DC generator through the action of a commutator, which converts the alternating current induced in the armature windings into direct current by reversing the direction of current flow at the appropriate times. As the armature rotates within the magnetic field, the commutator ensures that the output current remains unidirectional, resulting in a DC waveform at the generator terminals.

AC generators have a varying waveform which is sinusoidal in nature, whereas a DC output is linear.

Comparator is basically,which allows more than one voltages and currents to be in its output...
