Clipping on an amp can be caused by many different things the most common problem is that the amp is being over driven try decreasing the input voltage, and sometimes its the part value inside the amp try changing capacitors or resistors but only if you know how to do so if you are not trained don't attempt this or you may destroy your amp
ANSWER: Clipping is really caused by over driving an amplifier to both B+and/or B- saturation BY EXCESSIVE INPUTS

What component develops the output signal in a common emitter amplifier?
The voltage drop across the emitter-collector junction develops the output signal with the help of a resistor or two in series. The output is 'seen' at the collector.
What is a Scaling amplifier?
3-63A SCALING AMPLIFIER is a special type of summing amplifier with the output signaldetermined by multiplying each input signal by a different factor (determined by the ratio of the input-signal resistor and feedback resistor) and then adding these products
What is slew rate?
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
What is amplifier and types of amplifiers?
Amplifiers are electronic device that responds to a small input signal (voltage, current, or power) and delivers a larger output signal.
What is a Stereo Power Amplifier?
A stereo power amplifier is simply a two channel power amplifier. You can runn it in a couple of ways; Stereo, mono or bridged. Stereo has a seperate left and right signal in and sepetate out. Mono is one channel in and both output channels reproducing the one signal in. Bbridged gives you the same as mono BUT it uses both channels as one output.
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
What is the output signal of a common base amplifier?
3Db
Are amplifiers input or output devices?
An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
How do you over drive the amplifier?
you overdrive it by clipping it, by having the input signal being to strong. anything above -0db on the amp is clipping, so be careful.
What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?
Answer is GAIN
What is use of negative feedback in amplifier?
Reduce the distortion in output signal.
Why is the output signal affected if the impedance of the amplifier and the load do not match?
A: The signal output will not change it is just that the efficiency of power transfer is effected to less
What is the Effect of quiescent point close to cutoff?
The output voltage swing will not reach its maximum. This would then give clipping of one side of the signal which means the signal output is not a amplified representation of the original signal.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
Am amplifier that inverts the signal between input and output is called a what?
common emitter
Why signal distorted after amplification?
Distortion can be caused by many things, and varying levels. Two of the most common are;- Clipping. This is when the amplifier has reached maximum or minimum amplification and causes the wave form, to be flat top and bottom. It squares the waveform and sounds rough. Usually due to the input signal being too high. Harmonic. This is a form of feedback, where the input is receiving signal from the output. Sometimes the amplifier 'rings' at a harmonic of the input and is re-amplified giving a tinny, squeaky, sound. Caused by bad screening or component layout.
