摘要 |
In one embodiment, the present invention includes a method for determining when a step change occurs to a control value for a numerically controlled oscillator (NCO) providing a mixing signal, mixing the mixing signal with an input radio frequency (RF) signal to obtain an intermediate frequency (IF) signal and demodulating the IF signal into a demodulated signal, generating a correction value based on the step change, and applying the correction value to the demodulated signal. Other embodiments may be used to cancel other undesired signal portions, such as impulse spikes generated from the NCO change.
