Abstract

FM demodulators using Digital Signal Processing (DSP) are smaller and more reliable than conventional analog FM demodulators. The authors have already proposed an improved tangent‐type FM demodulator (I‐TAN) capable of extending the demodulation range without introducing distortion. This paper proposes a new range‐extended TAN‐type FM demodulator (RE‐TAN) capable of extending the demodulation range for wideband FM signal without increasing the sampling rate. The range can be extended incrementally by increasing the number of stages of the range extender proposed in this paper.
