A method and apparatus process an input signal along two paths so as to reject image signals created during processing. On the first path the input signal is mixed with a first component of a first local oscillator signal to generate a first signal at a first, non-zero intermediate frequency, the first signal is filtered, and the filtered first signal and a first component of a second local oscillator signal are mixed to generate a second signal at a second intermediate frequency, wherein the second intermediate frequency is higher than the first intermediate frequency. On the second path the input signal is mixed with a second component of the first local oscillator signal to generate a third signal at the first intermediate frequency, the third signal is filtered, and the filtered third signal and a second component of the second local oscillator signal are mixed to generate a fourth signal at the second intermediate frequency. An output signal is generated as a function of the fourth signal and the second signal in which output signal the image signals have been reduced.
