Radio Interference Suppression in a Vehicle with Car Radio Receiver

The article describes the technique of interference measurements in a wiring systems of vehicles which is useful in assessing the conditions of the compatible operation of a car radio-receiver. Research shows that a cur­ rent probe is a particularly useful instru­ ment in the measurement of such interferen­ ces. Results of appropriate measurements are given, together with conclusions concerning an efficient and economical interference sup­ pression method for the satisfactory opera­ tion of a car radio-receiver. Also discussed are the reasons for the different efficiency of an individual suppressor at the same fre­ quency in various types of engine electrical installation.
