To easily do that all you need is a higher voltage level or the level that you desire . square waves usually are states of [1] or rail voltage and on[0] saturation voltage. to linearly amplify these square waves you will need a hi band pass amplifier . Possibly 50megahz or so
transitor
A scope is nothing else then a display instrument it will amplify and display a signal on a CRT for visual analysis
An amplifier will amplify a signal. For example, the antenna in a radio will receive an extremely weak signal; before it can be converted to a sound, it must be amplified (made stronger), by a factor of several million. Of course, since you can't produce energy out of nothing, an amplifier doesn't actually produce the energy for the strong version of the signal - it requires a power supply.
transformers cannot amplify!
AC sinewave
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
Amplify is a verb. This device amplifies the signal from the microphone so that it can be heard.
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
ac and dc
to amplify the input pneumatic signal
they amplify the phone's incoming signal
I think Amplifier is use for direct signal or D.C signal & the main function of amplifier is to make that signal sharp(powerful) so that a microprocesser process it.
An amplifier that is designed to amplify the signal from an electric guitar and drive a speaker to convert that signal to sound.
The work of a transistor is to amplify the input signal to get high output value.
Transistor is an active element because it can amplify the signal applied.
A bipolar junction transistor (BJT) can amplify DC signals, but it requires proper biasing to operate in the active region. By applying a DC input signal to the base, the BJT can control a larger DC current flowing from the collector to the emitter, effectively amplifying the input. However, the amplification is limited to small variations around the bias point, and the BJT cannot amplify a constant DC level without an input signal. Therefore, while BJTs can amplify DC, they are primarily used for AC signal amplification.
