Design and Development of a Superheterodyne Frequency Modulation Radio Receiver Using TDA7000IC (88MHz – 108MHz)

This paper is based on the design and development of a superheterodyne frequency modulation radio receiver using an integrated circuit TDA7000IC for its implementation. The TDA7000IC is used because of the multifaceted function it has such as Radio Frequency, Local Oscillator, Mixer, Detector/Demodulator, Amplitude Modulation amplifier, Limiter, Correlator. The tests of reception of signal were carried out in three different areas of Lagos State to determine the level of signal reception and striking results were obtained in Ibeju Lekki and Ikorodu but fairly results were obtained in Epe area due to the topographic nature of the area. This design finds its usefulness in rural areas where there is no access to television sets in order to disseminate information about the happenings in the country.
