Abstract
A simple scheme is proposed for detecting tone signals narrowly spaced in frequency. By employing Teager´s energy tracker as a preprocessor, the tone detector can be implemented without the use of sharp notch filters. The proposed detector is applied to distinguishing ITU-T V.8 and V.25 tone signals. The detector performance is analysed and verified by computer simulation
