Instantaneous Frequency Measurement Method Using Phase Shift on Delay Devices
Suminori Nishie, Masato Akagi (JAIST) EA2013-93
Abstract (in Japanese) (See Japanese page) 
(in English) We have devised a precise frequency measurement method called PRIMO. It was proven that PRIMO has high frequency resolution by using IIR comb fillter. However the comb filter essentially has in finite impulse response, therefore the accuracy in time domain was not appropriately evaluated.
Moreover, PRIMO has a drawback in estimating instantaneous amplitude inside PRIMO for required measurement accuracy. In this paper, we propose an instantaneous frequency method by two simple signal delays for frequency-phase translation in order to establish the finite-time measurement. This paper also reports the evaluation of the proposed method by FM modulated signals mainly in acoustic frequency ranges.
