The FM stereo transmitter circuit described below can be used for broadcasting a crystal clear stereo FM music to all nearby FM radios. FM basics Most of the basic wireless […]
Transmitter Circuits
All devices that are designed to send and receive signals from two distant set ups for implementing an intended operation without using physical wires or contact across the two installations are called wireless systems, and the involved gadgets are called wireless devices.
Under this category you will find some amazing related circuits mainly based on FM wireless transission.
FM stands for frequency modulation and today most of the wireless based devices are controlled using FM signals at different frequency levels.
Here you will comes across a vast range of designs starting from the most basic ones suitable for new hobbyists to the relatively complex ones designed for the engineering students and experts in the field.
You will find some interesting FM remote control circuits which could be used for remotely operating an intended job such as doors locks and safes, you will also discover a few sophisticated GSM based highly advanced remote controlled systems working through cellphone networks.
