What is a RF amplifier?
A RF amplifier is a device for electrically amplifying the power of an electrical signal, typically, but not exclusively, radio frequency signals.
What are the feature that effect the frequency response of an amplifier?
all reactive elements in the amplifier, including stray capacitances and inductances.
Tell you what an intermediate frequency amplifier do?
The intermediate frequency (IF) amplifier lies between the mixer and the demodulator. The mixer shifts the input radio frequency (RF) signal into the range of the IF amplifier. The IF amplifer is a band pass amplifier, so only RF signals that are the IF frequency distance away from the local oscillator in the mixer can pass through to the demodulator. This process is called the superhetrodyne process.
What is the effect on analog signal by increasing its gain?
There is no effect on frequency but the amplitude is increased
What is frequncy responce of common emitter amplifier?
It is the range of frequencies over which the amplifier works as designed. It is limited at the lower end by coupling capacitors in series with the signal, and at the high end by capacitance in parallel with the signal.
What effect does an amplifier have on the frequency of the signal?
A; An amplifier will have no effect on the input frequency however its output may not follow the input frequency at the hi end due to the amplifier limitations
Why do you need small signal amplifier?
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
What is amplifier and oscillator?
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.

Why won't a satellite TV in-line amplifier boost a DTV signal in a fringe area?
Most likely it's because the satellite amplifier doen't have the bandwidth or frequency range to cover the DTV signal.
What is the effect on analog signal by increasing its gain?
There is no effect on frequency but the amplitude is increased
What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
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 is the difference between a Superheterodyne and a Neutrodyne radio receiver?
The superheterodyne converts the desired incoming signal frequency to an (usually lower) intermediate frequency before demodulating it and extracting the audio signal (or video/data, etc).The neutrodyne is a tuned radio frequency design where all amplifying stages operate at the incoming signal frequency. This was the commonest design up to the 1930s. The triode amplifiers used suffered from signal feedback, where a signal from the amplifier's output was coupled back to its input. This could cause the amplifier to act like a transmitter and to oscillate. Neutralization (with capacitors) was invented to prevent this problem and the circuit was named the "neutrodyne".
