Amplification is process through which weak input signal is amplified to a larger level. In today’s post, we will have a detailed look at the amplifier circuit using BJT. We will make a complete amplifier circuit and discuss all its parameters. So let’s get started with the BJT as an Amplifier. BJT as an Amplifier. DC and AC Quantities

Bode. Run the frequency-domain analysis to see a plot of the gain of the amplifier. As-is, it's about +38dB in the passband. That's a voltage gain of 10^ (38/20) = 79. Notice that our hand calculations indicated a gain of about 88, so that's pretty close! Now remove CE, and re-run the Bode analysis.

The BJT transistor is a current amplifier when the base emitter voltage is 0.6~0.7V like a diode drop. The collector-base is also a diode but is only lightly doped and reverse biased to function as a bas current controlled current amplifier.
Simple Audio Amplifier : 5 Steps - Instructables
https://www.instructables.com/Simple-audio-amplifier/
In most cases first project in electronics for beginners is building simple audio amplifier. That is because it requires small number of elements and not a lot of knowledge to build one. For low power amplifiers we could use integrated circuits like TDA family. But I will show how to make amplifier using operational amplifier.
