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.
Circuit for single tuned amplifier?
A single tuned amplifier basically consists of a tuned circuit (which may consist of an IFT or a parallel tuned LC circuit) connected to the collector of an amplifier circuit (in Common Emitter configuration). The tuned circuit is designed to get a resonant frequency equal to the incoming frequency signal that arrives at the base. The Single Tuned Amplifier gives maximum amplification to that particular incoming frequency which matches the resonant frequency of the tuned circuit and attenuates all other frequencies. Thus it gives sharp selectivity with a high Q-factor.
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier signal.
What is class c tuned amplifier?
Class C tuned amplifier is a large signal tuned amplifier that amplifies high power signals of the radio frequency range. The amplifier is said to be Class C if the output cycle obtained is less than half a cycle of the full input cycle. This means the transistor remains active for less than half a cycle so that only that much part of the input waveform is reproduced at the output with amplification. For the remaining part, the transistor remains inactive.
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.
Which device amplifies the incoming signal and noise?
Amplifier repeater
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
What does a Car Amplifier do?
It "amplifies" the signal of your stereo so it is louder to hear.
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
Is repeater an amplifier?
A repeater that does not distinguish between noise and signal; it amplifies both.
What is small signal amplifier?
As the name suggests, it amplifies a small signal. It ususally has a very high input impedance, to avoid affecting the source signal.
What is the use of an amplifier?
Increase the incoming signal between every even distance
What is the use of the amplifier?
Increase the incoming signal between every even distance
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 does amplitude increases in an amplifier?
Amplitude can increase in an amplifier by boosting the strength of the input signal. This is typically achieved by providing additional power to the signal through the amplifier, causing the output to have a higher amplitude than the input. The amplifier amplifies the signal by multiplying it by a constant factor known as the gain, which determines how much the amplitude is increased.
