I dont know exactly... Its may be because we need it!!
Darlington amplifier has more gain when compared to cascade amplifier .
Over all feedback
Cascade connections refers to the series connection of amplifier stages, networks, or tuning circuits in which the output of one feeds. The cascade connection is also known as the tandem connection.
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
In a cascade amplifier, two identical or non identical amplifiers are cascaded ,i.e., connected in series through a capacitor. They are mostly common emitter amplifiers that are cascaded together.The final gain of the cascaded amplifier is the product of the first amplifier's gain and the second amplifier's gain. However, the bandwidth of the cascaded version becomes lesser than the individual gains.
A Audio Video Cascade on a Video Distribution Amplifier (VDA) is a passive connector that allows the input signal to be passed through unamplified to another VDA. For example, this allows you to connect two four-channel VDA's together to have 8 outputs.
You need an amplifier for any speakers if they are to function.
A mono amplifier. You need two for stereo.
How do you replace the amplifier in a 2002 ml 500? i need to know where in the 2002 ml500 i can find the audio amplifier
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .
You DO NOT need an amplifier for a dj setup. Some speakers now come with a built in amp, known as a "POWERED SPEAKER".
you need an amplifier for any electronic drumset unless u wanna use earphones
