The subwoofer is the actual speaker making the loud bass. The amplifier is what powers the subwoofer and makes it work how it does. It only uses the low frequencies from the audio source and amplifies it.
A Darlington pair is two transistors connected to give a very high current gain
All negative feedback systems, whether they be electronic, biological, or anything else, work by applying a negative feedback to the source signal, which is proportional in some way to the source signal. If the factor by which the amplifier corrects is high enough, oscillation will result (perhaps even runaway oscillation) How you make it happen depends upon the amplifier you use however -- though most work similarly enough. You could use a delay between output and feedback, or you could rely on a large amplifier gain.
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
Darlington circuit is voltage follower circuit with high input impedance and low output impedance.Darlington IC must have this ciruit integrated on it..
Darlington amplifier has more gain when compared to cascade amplifier .
lauda
No. It uses triple-Darlington amplifier stages, and has a rated frequency response only down to 10Hz. It cannot amplifier 0Hz (DC) inputs.
Connecting a resistance btw the o/p and i/p of the amplifier to increase the i/p impedance is called bootstrapping..
An amplifier will power your subwoofer so they can work.
A passive sub-woofer does work when plugged in to an amplifier. In an active sub-woofer ("powered") the amplifier is built in.
A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.
what does it mean by rotating amplifier and how it works?
