The out-of-band radiation power of certain forms of RF signals

Increasing demand for the electromagnetic compatibility of radio systems requires detailed investigation of RF signal spectra and determination of their out-of-band radiation power concentrated at frequencies outside the required bandwidth. A procedure is proposed for determining out-of-band radiation power of the control Rf signal generated by keying the high-frequency carrier in amplitude (ASK), frequency (FSK), or phase (PSK) by a unipolar meandering video signal (the sequence of symbols '1' and '0').
