Superheterodyne AM Receiver Circuit Now, we know the basic functionality working of a Superheterodyne Receiver, let’s take a look at a typical circuit diagram of Superheterodyne Receiver. The below ...

The schematic diagram shows an audio stage with a common-collector circuit. This does not damp the tuned circuit, but instead actually increases its response. This yields good sensitivity and ...

NPN Transistor Switching Circuit Before starting with the circuit diagram, you should know the concept of NPN transistor as a switch. In an NPN transistor, Current starts flowing from collector to ...

Schematic visualization is important for analog circuit designers to quickly recognize the structures and functions of transistor-level circuit netlists. However, most of the original analog design or ...

The last chapter will provide a trip down memory lane for some readers—a sampling of circuits of particular interest in RF history, including the Regency TR-1 transistor radio design and the ...

FM Receiver Circuit Explanation Here’s a simple FM receiver circuit with minimum components for local FM reception. Transistor BF495 (T2), together with a 10k resistor (R1), coil L, 22pF variable ...
