Abstract
A switched-capacitor (SC) adaptive spectral analyzer is described that has power-determined frequency resolution. Using commercially available SC filters, the circuit is capable of real-time analysis of input spectra below 150 kHz. The time window analyzed and the tracking speed are user selectable
