Which amplifier has largest bandwidth?
Direct coupled amplifier
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
Basic theory of two stage RC coupled amplifiers?
connections are to be made per the crkt the main of this crkt is to make strong or to bost the signal comming to the crkt input is given with ac supply and they are connected to resistor and capacitor when the ac suppply is given it contains slight amount of dc supply so to block the dc supply capacitor is used and the dc supply is given at the collector so that resistor present at c and ground gets biased then another capacitor used at c to ground for removing the dc supply then out put seen on cro across collector to ground we get the perfect amplified signal the more we give the coupled amplifer the most amplfed sgnal we get
Why gain is fall at high frequency in r-c coupled amplifier?
The gain of an r-c coupled amplifier falls at high frequency because the capacitive reactance of the capacitor tends to zero.
What is chopper amplifier?
In a chopper type amplifier the dc i/p voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional to the original i/p signal
Which amplifier has largest bandwidth?
Direct coupled amplifier
Is the audio-source 310 amp direct-coupled?
No. It uses triple-Darlington amplifier stages, and has a rated frequency response only down to 10Hz. It cannot amplifier 0Hz (DC) inputs.
What is meant by RC coupled amplifier?
an amplifier, where the resistor and capacitor get coupled to provide high oscillations hence by which amplifications increases at high degrees
Theory of RC coupled Amplifier?
In a two stage RC coupled amlifier the rransistor are identical and a common power supply is used. the output is provided to the first stage of the amplifier wher it is amplified and this output is uses as a input for the sexound stage this is amplified once again by the other transistor in the sexound stage and the final out put is obtain.
Circuit diagram of RC coupled amplifier?
One of the several uses of an RC coupled amplifier is to amplify the given input signal. It makes use of a sinusoidal input signal.
What happens if you remove emitter resistor in RCcoupled amplifier?
what happens if we remove Rc in RC coupled amplifier
What happens if amplifier is connected t a DC voltage?
It will depend on the which kind of amplifier it is ,if it is made from Op amp(Non inverting Amplifier) it will simply amplify(multiply)the signal with a factor depend on the configuration of circuit which is also known as gain of the circuit.For instance if gain is 2(dimension less) and input DC voltage is 2 Volt output would be 4 Volts. and if it an Audio or RC coupled amplifier output would be zero Hence i Wrote in the starting "It will depend on the which kind of amplifier it is"
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
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
