Circuit simulation made easy. A free online environment where users can create, edit, and share electrical schematics, or convert between popular file formats like Eagle, Altium, and OrCAD. Transform ...

The circuit exemplifies the use of ZN414 IC to produce a handy AM radio receiver. ZN414 IC– a composition of transistor tuned radio frequency (TRF) circuit packaged in a 3-pin TO-92 plastic package ...

This AM receiver circuit is based ob the IC ZN415 introduced by Ferranti. This IC is an improved version of the early ZN414. It is a complete AM radio receiver and does not need IF transformers and ...

Next, this is another FM radio receiver circuit that has a two-transistor configuration. But like the previous circuit, this circuit uses two 2N3904 general-purpose transistors to generate the ...

In normal operation jumper JP1 is set to bridge pins 2 and 3, which connects the end of the FM coil to the AM input. What is not visible from the circuit diagram is that in FM mode the receiver sets ...

A modeling methodology for macro-modeling transistor level receiver circuits has been proposed. A few receiver modeling techniques have been proposed in the past, but these modeling techniques only ...

This paper researches on some key technologies of anti-jamming of an air-borne radar receiver, the automatic testing of AGC, IAGC and multi-filtering under one million noisy pulses by the computer ...
