What happens when the input frequency changes?
If the input frequency is increased, this will droop less between half-cycles, and so increase output voltage slightly. The transformer may have a low primary inductance, and be loading the input supply. Raising the frequency will reduce this effect, and raise the output voltage slightly.
What is the effect in output for changing input signal frequency for both the circuits?
The output signal completes a period twice as fast as the input frequency, as you can see in the diagram. So ,frequency ,f=2f .
What happens if the input frequency is kept lower than the frequency at which the gain is zero?
What happens if the input frequency is kept lower than the frequency at which the gain is zero? Explanation: If the input frequency is lower that the lower frequency limit of the integrator (i.e. when gain = 0), there will be no integration results and the circuit act like a simple inverting amplifier.
For what kind of input signal the frequency divider can be avoided frequency multiplier?
3. For what kind of input signal, the frequency divider can be avoided frequency multiplier? Explanation: VCO can be directly locked to the nth harmonic of the input signal without connecting any frequency divider in between the input signal rich in harmonics like square wave.
How does frequency affect a diode?
During the recovery time there is high reverse current through the diode. This reverse current makes the diode to produce some heat. The higher the frequency is, the more time is spent in the recovery state and so the more heat is produced by the reverse-recovery process.
What is the effect of frequency on diode?
The effect of series resistance on the capacitance is found appreciable at higher frequencies when capacitance decreases rapidly with frequency. On the other hand, the conductance of the diode increases with frequency in the high frequency limit.
What is the frequency of output signal of full wave rectifier if the frequency of input signal is 50Hz?
100 Hz
So, if the input frequency is 50 Hz, output frequency will be 100 Hz.
What will be the output frequency in the full wave rectifier if the input frequency is f Hertz?
Half-wave rectifier conducts once during a cycle and full-wave rectifier does so twice. Therefore, if input frequency is 50 Hz, output frequency for half-wave and full-wave rectifier are 50 and 100 Hz respectively….Semiconductor Electronics: Materials, Devices and Simple Circuits.

What is the value of output frequency if input frequency of signal supply of full wave rectifier is 50Hz?
What are the two types of signal rectifiers?
There are two types of signal rectifiers, half-wave and full- wave. Let’s first consider the ideal half-wave rectifier. Pretty simple! When the input is negative, the output is zero, whereas when the input is positive, the output is the same as the input.
How does a full wave rectifier work?
A full wave rectifier converts negative input signal also to positive in output. Thus in input in one cycle you have only one positive signal while in output of one cycle you will notice two positive signal. That means the period of signal in output gets halved while frequency of the signal in output gets doubled to that in input.
What is the frequency of the rectified signal?
Since the signal to be rectified is usually symmetric in nature, the frequency of signal at output is doubled. Also, rectification is a process of converting alternating current into unidirectional current. It is a part of DC power generation unit. In a direct current, we ideally require a zero frequency signal.
What is the frequency IF AC is rectified?
Rectification is a process which converts AC current to DC current, therefore, we can not call it a frequency if AC is rectified. After rectification half-wave or full-wave, the output is a Pulsating DC. If you connect a CRO to the output of Rectifire , you will see continuous trail of half wave pulses.
