This third volume of the book series Lessons In Electric Circuits makes a departure from the former two in that…
Active Devices An active device is any type of circuit component with the ability to electrically control electron flow (electricity…
Benefits of Active Devices The practical benefit of active devices is their amplifying ability. Whether the device in question be…
Voltage Gain Because amplifiers have the ability to increase the magnitude of an input signal, it is useful to be…
It is also possible to use the decibel as a unit of absolute power, in addition to using it as…
In its simplest form, an amplifier’s gain is a ratio of output over input. Like all ratios, this form of…
What is Attenuator? Attenuators are passive devices. It is convenient to discuss them along with decibels. Attenuators weaken or attenuate…
