An RF amplifier amplifies the incoming signal by 200 times Calculate the power gain of this amplifier in dB?
If an RF amplifier amplifies the incoming signal by 200 times, the power gain of the amplifier is +25.9 dB. Power is proportional to voltage squared, so the power gain is 400. The decibel scale is 3 times log2 of the power change.
What is CMRR of differential amplifier?
CMRR stands for Common Mode Rejection Ratio, and it is a measure of how well the amplifier rejects signals that appear on both leads. The idea is that an amplifier should amplify the (Differential Mode) signal, but not any noise (Common Mode) that might appear on the lines, perhaps due to induction from nearby AC power sources. Since induction will show up on both leads, a high CMRR amplifier will have a greater signal to noise ratio overall
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
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 the advantage of a bidirectional cable amplifier over a unidirectional cable amplifier?
A biderectional cable amplifier with a bypass is excellent for use with digital TV, because it amplifies the return signal. Using a unidirectional cable amplifier can result in some channels that do not work because the return signal is not amplified.

Whats the main difference between small signal amplifier and large signal amplifier?
1.Small signal amplifier can be designed easily using s parameter while large signal amplifier not.
What does a negative dB mean when evaluating the performance of a line?
Loss of signal strength
Are there any cables that help out with the signal strength of my antenna and converter box?
Try the Winegard HDP-269 High Input Pre-Amplifier 12 dB Digital Antenna.
You will have signal degradation unless you use the amplifier.?
You will have signal degradation unless you use the amplifier.
The voltage gran of an amplifier is 200 The decibel voltage gain is?
The voltage gain of an amplifier is 200. The decibel voltage gain is? Answer Gain in dB = 20 * log 200 = 46 dB
In amplifier is voltage amplify or only signal of voltage amplify Please give answer in simple englisH IN SIMPLE English an amplifier doesn't need to amplfy any signal to be an amplifier it can be us?
I think Amplifier is use for direct signal or D.C signal & the main function of amplifier is to make that signal sharp(powerful) so that a microprocesser process it.
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
Can you improve voltage level in the range of millivolt into a 15volt?
A voltage amplifier (high input and output impedances) with a gain of 83.5 dB will amplify a signal of 1 millivolt to an output of 15 volts.
Where can one book a cell signal amplifier?
A cell signal amplifier can be easily booked on technology websites such as Bestbuy, however one can also buy a cell signal amplifier via websites such as Amazon.
What does dB equals to?
dB (decibel) is a logarithmic measure of the ratio of two power values, for example, two signal strengths. This is often used for power gain or power loss. For example, a loss of 10 dB means that the signal degrades by a factor of 10, a loss of 20 dB means that the signal degrades by a factor of 100, and a loss of 30 dB means that the signal degrades by a factor of 1000.
