Why electrolytic capacitors are used for frequency response of BJT as amplifier?
It can take a lot of capacitance to present a low impedance to a low frequency. Electrolytics offer lots of capacitance for a low price.
What is Cascaded BJT amplifier?

What are the feature that effect the frequency response of an amplifier?
all reactive elements in the amplifier, including stray capacitances and inductances.
What are the steps involved in finding the signal gain for a common-emitter BJT amplifier?
The signal gain of a CE BJT amplifier is hFe or collector resistance divided by emitter resistance, whichever is less.
What is the effect of bypass capacitor on frequency response?
Gain in a CE configuration of a BJT is collector resistance divided by emitter resistance, subject to the limit of hFe. The emitter bypass capacitor will have lower impedance at high frequency, so the gain will be higher at higher frequency, making this a high-pass amplifier.

What is the purpose of determining frequency response?
frequency response curve helps us to find the bandwidth of particular amplifier circuit. Bandwidth is the range of frequency at which the amplifier works better....

What is the range of the amplifier's frequency response?
The range of the amplifier's frequency response refers to the range of frequencies that the amplifier can accurately reproduce. It typically spans from 20 Hz to 20,000 Hz, covering the audible spectrum of human hearing.
What are the feature that effect the frequency response of an amplifier?
all reactive elements in the amplifier, including stray capacitances and inductances.
How the frequency response of an audio amplifier can be determined using square waves?
If the square wave gets distorted a lot, then the frequency response is not good.To get more precise data, you really should not use square waves; since you want the frequency response, you need to test how the amplifier reacts to pure waves (sine waves) of different frequencies.

The signal gain of a CE BJT amplifier is hFe or collector resistance divided by emitter resistance, whichever is less.

What is high frequency tuned amplifier?
High frequency amplifier is a device which is tuned by high frequency. Tuned means the overlapping of generated frequency with that amplifier.
What is selective amplifier?
Selective amplifier is an RF amplifier which selects particular frequency and amplifier so it can operate at fixed frequency.
Which bjt transistor amplifier can be used as a voltage buffer?
the common collector can use as voltage buffer
What effect does an amplifier have on the frequency of the signal?
A; An amplifier will have no effect on the input frequency however its output may not follow the input frequency at the hi end due to the amplifier limitations
