After analyzing the spectrum of the FSK signal and finding the feasibility to apply band pass sampling technology,a new real time detection for FSK signal based on non whole period sampling is put forward,and the frequency resolution and the character of real time are also studied.

Application of band-pass sampling technology in high resolution imaging sonar;

Selection and Kind Optimization for Band-pass Sampling Rates in Digital Receivers;

interpolate and extraction,and applying band-pass sampling in bandwidth digital instruments,the requirement of A/D converters used in these instruments can be reduced dramatically.

This article introduces the mobile communication base station receive subsystem one wide band intermediate frequency bandpass sampling software radio technology realization method.

In this paper,bandpass sampling technology widely used in software defined radio is studied.

It is in accord with software radio, bandpass sampling and coherent demodulation techniques are used in the demodulation, and also make analysis with the spectrum.
