DRM Digital Radio Receivers Sensitivity

The article is devoted to the issues of ensuring the necessary sensitivity to the electromagnetic field of DRM digital radio broadcasting receivers. Measuring installations have been created and measurements of the DRM receiver samples sensitivity from the external antenna input and the electromagnetic field have been carried out. The sensitivity from the external antenna input corresponds to planned values, but for the electromagnetic field in the Low Frequency and Medium Frequency ranges, it does not. A method has been developed for calculating the DRM receivers input circuit, which makes it possible to ensure the required sensitivity value for the electromagnetic field.
