Polar frequency discriminators (PFD) are widely used in radar and direction-finding applications to determine the unknown frequency of incoming pulses. This article explains how to design the RF ...
Sounds are decomposed to different frequency bands by the auditory periphery. Tonotopic (‘by frequency’) organization is kept throughout the auditory pathway, at least up to and including primary ...
The circuit was designed to produce a frequency multiplier for low frequency from the measurement of their signals while eliminating the noise that comes with them. CA3130 – a BiMOS operational ...
