If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...
As a vendor for high-end test and measurement solutions used in mobile radios and radio communication, Rohde & Schwarz depends on the availability of proprietary ASICs delivering key functionality and ...
Researchers reveal novel mechanisms for decoding bacterial frequency modulation in signal processing
Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...
