Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
What is the function of an attenuator in cro?
An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. attenuator just decrease its amplitude and the attenuator you can take it as a opposite of amplifier. Amplifier just modifies the input signal gives amplified output signal
What is the common ratio for the following sequence 648 - 108 - 18 - 3?
The "common ratio" of a geometric series is any of the numbers, divided by the previous number.If in all cases you get the same ratio (the same result of a division), then you have a common ratio. If the division gives you different numbers, then there is no common ratio.
What is the GCF 304 and 475?
The GCF of 304 and 475 is 19. This gives you 16 and 25 respectively. You cannot get any more common factors that impact the end figure.
What is the GCF of 52 and 72?
4 is the greatest common factor of 52 and 92.
Why is common emitter is greater than common collector?
Common-emitter gives more voltage gain because a common-collector amplifier has a voltage gain of 1. But a common-collector can have a power gain because the input impedance is much more than the output impedance.
Which transistor mode gives the inverted output?
common-emitter
What are common uses of a common emitter amplifier?
bcause amplification factor beta is usually ranges from 20-500 hence this configuration gives appericiable current gain as well as voltage gain at its output on the other hand in the Common Collector configuration has very high input resistance(~750 kilo ohm) & very low output resistance(~25 ohm) so the voltage gain is always less than one & its most important application is for impedance matching for drivingh from low impedance load to high impedance source
Why is a common collector used in the last stage of the amplifier?
becoz it gives good gain which is necessary for an amplifier.
Circuit for single tuned amplifier?
A single tuned amplifier basically consists of a tuned circuit (which may consist of an IFT or a parallel tuned LC circuit) connected to the collector of an amplifier circuit (in Common Emitter configuration). The tuned circuit is designed to get a resonant frequency equal to the incoming frequency signal that arrives at the base. The Single Tuned Amplifier gives maximum amplification to that particular incoming frequency which matches the resonant frequency of the tuned circuit and attenuates all other frequencies. Thus it gives sharp selectivity with a high Q-factor.
What is the working of a Darlington amplifier?
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
Which coupling gives high gain in case of amplifier?
no.transformer coupling gives higher gain
Is a microphone input or output?
input. The microphone gives a signal to the computer/radio/whatever you're using. it is input because when you speak into it,it gets in the amplifier and the amplifier processes it to came out as sound through the speaker

Does wattage affect the sound of an amp apart from volume?
An amplifier amplifies the input voltage. That gives you more volume.
