ABSTRACT:
A digital cueing radio receiver system embodied using digital memory in lieu of analog delay lines and thereby avoiding delay line implementation difficulties. The cueing receiver system includes a wideband receiver portion providing an output signal employed for tuning a narrowband receiver portion of the system. Signal delay enabling use of the wideband receiver portion output signals for tuning the narrow band receiver portion selection frequency is provided by a digital memory circuit operating on analog-to-digital converted samples of input signal data of the receiver system. Approximated unity value related mathematical multiplication free Kernel function values are employed in the Fourier transformation. Avoidance of analog delay line-elements in embodying the system is a significant practical advantage of the invention.
