Abstract
The signal strength of an out-of-channel interferer is estimated by measuring the transition density of the sign of the down-converted signal. RF interferers at a higher or lower frequency than the desired RF signal appear as high frequency content in the down-converted signal, thus increasing the likelihood of zero-crossings.
