Why the peak value in double ended differential amplifier is double the peak value of single ended differential amplifier for the same input signal?

The peak output value in a double ended differential amplifier is double the peak output value of a single ended differential amplifier for the same input signal because there are two outputs, one being the normal output, and the other being the inverted output. Whatever the normal output does, the inverted output does, but with a reverse sign. As a result, if one output has a value of X, then then other output has a value of -X. If you compare the two outputs, then, the difference between them will be 2X, or double the value.

Why does an operational amplifier need a power supply?
It doesn't. You can make a differential amplifier with a single power supply.
Why is differential amplifier preferred over single ended amplifier?
The input stage of an op amp is usually a differential amplifier; this is due to the qualities that are desirable in an op amp that match qualities in a differential amplifier: common noise rejection ratio; low input impedance, high output impedance, etc. The use of differential amplifiers in op-amps is to increase the input range and to eliminate common entries like noise.
Is there electrical equipment can sum 3 dc signals to get 1 output signal?
An operational amplifier can sum an arbitrary number of signals and produce a single output signal.
What is the function of resistor in single stage amplifier?
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.
What is advantage and disadvantages of multistage amplifier?
A multistage amplifier is composed of several single stage amplifiers.
Why does an operational amplifier need a power supply?
It doesn't. You can make a differential amplifier with a single power supply.
Why high CMRR is preferred?
You want an amplifier to reject common mode signals (the same signal applied to both inputs of a differential amplifier) because:it is generally noise, which sounds like staticit can cause drift in the amplifier eventually saturating it, causing clipping distortionBTW, single ended input amplifiers by definition have a CMRR of zero.

What does a video amplifier do?
A video amplifier is a device that accepts a single input signal and provides this same signal to multiple isolated outputs. These devices are important because they allow signals to be distributed to multiple destinations without ground loops and signal degradation.
What does the OP stand for in OP amps?
Op amps stands for operational amplifier. An operational amplifiers is a high gain voltage amplifier that requires a differential input and produces single outputs.
Distinguish between op amp and differential amplifier?
Look up "op amp" on wikipedia, there is a good drawing near the bottom right. An op amp contains a differential amplifier as the first stage, but has multiple following stages that provide amplifier near ideal characteristics of high input resistance and low output resistance (it can drive more current than a single dif amplifier stage).
Is there electrical equipment can sum 3 dc signals to get 1 output signal?
An operational amplifier can sum an arbitrary number of signals and produce a single output signal.
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
How is negative feedback achieved in a single stage transistor amplifier?
A: Feedback is a signal fed back from the output like from collector to the base .
How does an op-amp differ from other amplifier suchas common emitter transistor amplifier?
A: They both use transistors. In actuality before an op amp becomes an op amp a discrete transistor made is made to provide it capabilities before it gets integrated into a substrate chip we call op amp. OP AMP have two input to work as a differential amplifier the input are bases closely match to provide virtual no voltage or current offset. Single ended amplifier has one input its reference is the signal source return.

What is the signal path for HDMI connections?
The signal path for HDMI connections can either be single link or double link. The single link is called type A/C.
