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 […]

An audio mixer is an electronic device for combining, and modifying audio signals. The modified audio signals are summed to produce some combined output signals. This project is titled design and construction of a 4-channel microphone mixer. A microphone mixer is an electronic console that is used to mix different recorded tracks by changing their volume levels, adding effects and changing the timbre of each instrument on the tracks. A […]
This work is on a four channel audio mixer with public addressing system. This system does the work of combining (for audio selection) and modifying audio signals (for public addressing). Audio mixers are also called mixing consoles and soundboards. Mixers are most often used by recording studios but are also typically used in live situations by live sound engineers. The aim of this work is to design and construct a 4-channel mixer wh […]
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 […]
