  • Radio receiver for forming a baseband signal of time-varying frequencies
    Patent number: 5428836
    Abstract: A radio receiver, and associated method therefor, for generating a baseband signal having signal component portions of time-varying frequencies. The oscillating signal generated by at least one of the local oscillators of down-mixing circuitry of the receiver is modulated by a low-frequency signal thereby to cause the resultant, baseband signal to be comprised of signal component portions of time-varying frequencies. Because the signal component portions of the baseband signal are of time-varying frequencies, attenuation of such signal component portions and resultant distortion of the received signal, as a result of undesirable notches in the frequency response of a radio receiver is avoided.
