What are the Difference Between AF Amplifier and RF Amplifier?
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Loading effect in RC coupled amplifier?
Loading of Rc coupled amplifier occurs, if you doesnt use coupling capacitors...... If avoiding input coupling capacitor the amplifier will load the function generator.. For more details go to http://mycircuits9.blogspot.com
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
Why transformer coupled amplifier is more efficient than RC coupled amplifier?
an RC coupled amplifier is basically used for voltage amplification , where the circuit currents are quite low. higher currents & voltages would mean more dissipation in the load resistors , which is essentially very lossy . The coupling amplitude to the next stage is ideally the same as the previous stage signal excursion. However if a transformer is used for coupling , both large voltages & current can be handled without incurring the dissipation of a resistive load. Moreover a coupling gain of the transformer primary to secondary ratio is also a bonus. also because of the possiblity of correct impedance matching on the primary & secondary side maximum power coupling is obtained. hence transformer coupling is more efficient in such applications. in high frequency applications transformer coupling , along with tuned circuits as applicable is the choice circuit.

What lens mount does a nikon d7000 have?
Nikon F mount (with AF coupling and AF contacts)
Why you use coupling capacitor in electronic amplifier?
It is used to couple output of one stage to input of next stage

What is the difference between transformer coupling and RC coupling?
RC COUPLING :- is the most Commonly used Coupling Between the two stages of a cascaded or multistage amplifier because it is cheaper in cost and Very compact circuit and provides excellent frequency response. TRANSFORMER COUPLING :- Impedence Coupling results in more efficient amplification because no signal power is wasted in Inductor L. Such Coupling has the drawback of being larger, Heavier and Costlier than the RC COUPLING. Impedence Coupling is rarely used beyond audio range . by : Muhammad zubair.... muet student of telecom.

What is the purpose of an AF power amplifier in a FM broadcast receiver?
After FM demodulation to the original AF signal it is necessary to amplify the weak AF signal to have enough power to drive speakers. That is the purpose.
