Q3. Input Voltage is 50v,I want 20v at output design a circuit
Add your answer
Q4. Input fre is 50MHz and I want half of the frequency at output design the circuit
Ans. 
Use a flip-flop to divide the frequency by 2.
• Use a D flip-flop with the input connected to the clock signal and the output connected back to the D input.

• The output frequency will be half of the input frequency (25MHz).

Q2. Types of clipper circuit
Ans. 
A clipper circuit is an electronic circuit that limits or clips the voltage level of a waveform.
• There are two types of clipper circuits: positive clipper and negative clipper.

• Positive clipper circuit limits the positive half of the input waveform.

• Negative clipper circuit limits the negative half of the input waveform.

• Diodes are commonly used in clipper circuits to perform the clipping operation.

• Examples of clipper circ...read more

Q3. Types of clamper circuit
Ans. 
A clamper circuit is used to shift the DC level of a signal without changing its shape.
• Positive Clamper: shifts the DC level of the input signal to a higher level

• Negative Clamper: shifts the DC level of the input signal to a lower level

• Biased Clamper: shifts the DC level of the input signal to a desired level using a biasing voltage

• Diode Clamper: uses diodes to clamp the input signal to a specific DC level

Q4. Clipper with the help of opamp
Ans. 
Clipper with the help of opamp is a technique used to limit the output voltage of a signal.
• Clipper circuit is used to limit the voltage level of a signal by clipping off the peaks.

• Opamp (operational amplifier) is a high-gain electronic amplifier used to amplify and manipulate signals.

• By combining a clipper circuit with an opamp, the opamp can be used to control the clipping level and shape the output signal.

• The opamp c...read more

Q5. Clamper with transistor
Ans. 
A clamper circuit is used to shift the DC level of a signal.
• A clamper circuit consists of a diode and a capacitor.

• It is used to add or subtract a DC voltage to a signal.

• The transistor can be used in a clamper circuit to control the clamping voltage.

• The transistor acts as a switch to control the charging and discharging of the capacitor.

• Example: A clamper circuit with a transistor can be used to shift the DC level of an...read more
