Make this Crystal Radio Set Circuit using No Batteries
A crystal radio circuit is probably the simplest form of radio that uses hardly any electronic components, and needs absolutely no external power for the operations. Crystal Radio Concept The only downside of this radio concept is the requirement of a very long antenna and a deep earthing, therefore this unit is not something which […]
5 Simple Preamplifier Circuits Explained
As the name suggests a preamplifier circuit pre-amplifies a very small signal to some specified level that can be further amplified by an attached power amplifier circuit. It basically acts like a buffer stage between the input small signal source and a power amplifier. A preamplifier is used in applications where the input signal is […]
