👍👍👍👍👍

[@willieandersson]

You make it so easy to understand👍🏻 that’s what great teacher do👏🏻👏🏻

Class d are being used in portable speakers/amplifiers due to weight & efficiency savings

Hi, what is difference between video amplifier and audio amplifier in equal circuit?thanks

[@michaelmounts1269]

Virtually every affordable amp etc on Amazon, Best Buy are all Class D. I personally don't like them...but they are a lot cheaper and take less power--and much less heat...

[@eitantal726]

The big deal about Class D amplifiers is the efficiency, as they avoid the linear region. A transistor inside the linear region is dissipating power. A transistor outside of this region (Off, or saturating) is not

Sir in class A amplifier why are they using cap and resistor to the emitter of the transistor.

[@pacurarualexandrumadalin8863]

for DC component of the signal, the resistor in the emitor will lower the amplification of the stage (Gain), for high frequency the reactance of the capacitor will short the resistor, so will increase the gain of the stage.

Kind of ironic: Talking about small signal amplifiers and having the noisiest microphone on whole KZbin. 🙂

[@mikesradiorepair]

What noise? Sounds fine to me.

These small electret mikes are rubbish. Nothing you can do about it.
