Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...
Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
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 ...
Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...
Abstract: A major targeted application scenario of molecular communication (MC) is information transmission in biological systems and in the human body in particular. These systems, however, are ...
Abstract: To achieve single-frame dynamic phase measurement, an error-free synchronous demodulation algorithm for two-dimensional pixelated spatial carrier interferograms based on the Butterworth ...
High resolution encoders are expensive, but alternatives exist. You can develop a high-resolution system using a sinusoidal encoder or resolver. Last month, we covered some of the basics of using ...
[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...
