A method for pre-compensating an analog signal in a composite digital audio broadcasting signal including the analog signal and a plurality of digitally modulated sub-carrier signal, the method comprising the steps (62) for sampling the analog signal to obtain successive sample blocks, a plurality of from the step 64 that demodulates the sample block, respectively so as to obtain a demodulator output, and step 68 re-modulates the demodulator output corresponding to the predetermined signal of the digitally modulated subcarrier signals to generate an error signal, one of the sample block removing the error signal comprises the step of generating a pre-step for generating a compensated sample block and pre-compensation for the compensated sample block in combination with a plurality of OFDM pulses composite signal. The method also includes apparatus for performing.
