The Goertzel algorithm can be used to compute the power of a single frequency. This algorithm is an implementation of the DFT for a single frequency and requires a single co-efficient which is related to the frequency to be measured and the sample rate. Refer to "Digital Signal Processing Applications using the ADSP 2100 Family", by Analog Devices Inc, p 458 for a simple explanation on how to implement. Contact your local Analog Devices rep to find a copy of this book Best of luck Steve
