Accurately measuring the amplitude of a sinusoidal signal is a design challenge that is common to many data acquisition designs. The most famous and ubiquitous solution to this problem is synchronous ...
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 ...
For the PDF version of this article, click here. This article will present three methods for using synchronous amplitude-modulated magnetic feedback for controlling dc-dc converter output voltage ...
Researchers reveal novel mechanisms for decoding bacterial frequency modulation in signal processing
This framework enables quantitative predictions about how cellular systems convert frequency-encoded signals into precise ...
This is the fourth in a series of articles about FM transmission systems. The bandwidth of a commercial FM broadcast signal, depending on whether or not subcarriers are used, is about 260 kHz. This ...
