single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage
this site has not given the answer of my question
It refers to the tuning a a multi-stage IF amplifier where successive stages are tuned to one side or the other of it's center frequency to create a wider bandwidth.
A: it could be both coupling meaning eliminate DC from the source or decoupling whereby unwanted signal is bypassed to ground
In a two stage amplifier the gain (ratio of the output to the input quantity) of the first stage is amplified again in the second stage so the gain of a two stage amp is the product of the gain of two individual stages which is sufficient enough to drive the output device as compared to a single stage amplifier.
A multistage amplifier is composed of several single stage amplifiers.
becoz it gives good gain which is necessary for an amplifier.
An 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.
in stage you have finsh one then start next, but in leve there is not this rule
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
