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.
Which amplifier uses the base as the reference terminal for the input and output signal?
The amplifier that uses the base as the reference terminal for the input and output signal is the common-base amplifier. In this configuration, the input signal is applied to the emitter, while the output is taken from the collector. The common-base amplifier is known for its high frequency response and low input impedance, making it suitable for specific applications such as radio frequency amplification.
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 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.
How does amplification affect frequency?
Amplification does not affect the frequency of a signal. It simply increases the strength or magnitude of the signal without changing its frequency. A properly designed amplifier will preserve the frequency content of the input signal while boosting its 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.
Draw and explain the super heterodyne receiver?
A superheterodyne receiver is a type of radio receiver that converts a high-frequency signal to a lower intermediate frequency (IF) for easier processing. It employs a mixer to combine the incoming radio frequency (RF) signal with a locally generated oscillator signal, producing the IF. This allows for improved selectivity and sensitivity through the use of filters and amplifiers. The basic components include an antenna, RF amplifier, mixer, local oscillator, IF amplifier, detector, and audio amplifier.
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.
