The early transmitter for radio broadcasting is so big and bulky that they do occupy numerous spaces. The circuitries are mainly designed with valves, which are big in sizes. With the advent of semiconductor materials such as transistors electronic equipment are now becoming miniaturized such that small transmitters are now becoming handy and compact. In line with this we choose to design a complete radio broadcasting equipment tat is […]

This work is design and construction of an Infrared (IR) based transmitter and receiver, which is a wireless communication technology. Infrared (IR) communication is used in remote controls of different appliances like TV’s. The handheld remote control of the TV consists of IR Transmitter and the IR Receiver is placed at the TV. An infrared transmitter and receiver consist of IR Transmitter and Receiver Modules. In this project, we bui […]
Radio transmitter is described as an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In […]
An FM transmitter is an electronic device which, with the aid of an antenna, produces radio waves. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. FM transmitter is basically a VHF colipits oscillator capable of transmitting sound or music to any standard FM receiver. The circuit works on a D.C source wh […]
