Amplifying Power with Transistors
Jonathan Bartlett · Apress eBooks · 2020
Amplification is the conversion of a low-power signal to a higher-power signal. Normally when we think of amplification, we think of sound amplifiers for musical instruments. Indeed those are amplifiers, and we will build a sound amplifier later in this book. However, anytime you convert a low-power input to a higher-power output, you have amplified the signal, whether that was a DC signal or an AC signal. In this chapter, we will focus on amplifying DC signals.
