Investigation of the Effect of Atmospheric Temperature on Signal Strength Generated by FM Transmitter in Imo State, Nigeria

Prince Chigozie Iwuji ^[2] | Donatus Enang Bassey

Abstract: This study reviews the effect of temperature on the signal generated by the frequency modulated transmitter of the Imo state broadcasting cooperation (Orient 94.4 FM) within some selected routes in Imo State, Nigeria. The research was carried out between the months of April and June 2016. The equipment used to measure signal strength in the study areas is a constructed Signal Strength Meter (SSM). Holo Ambient Temperature Pro {Thomas Otero (H3R3T1C) was used to measure the atmospheric temperature along the routes of signal measurement. Measurements were taken in different months, on different days, and at a different time of the day and different temperature. The average results of these measurements were then taken and the data obtained from the measurements were tabulated and subsequently plotted in a graph to ascertain the variation in signal strength along the different routes. It was observed from this research that the rise in atmospheric temperature will lead to a drop in strength of the signal generated by Orient 94.4 FM transmitter. Thus, it can be postulated that temperature varies inversely to the signal strength provided the transmission parameters remain constant.
