The circuit to create waveform like this is based upon a simple relay that is driven by a clock signal.

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

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 ...

In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

Continental has been granted a patent for a method of switching electronic components using pulse-width modulation signals. The method controls output signals through control signals, adjusting them ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Optical data transmission (ODT) offers a means of sending data between moving objects without some of the drawbacks associated with radio-frequency and wired-communications methods. ODT essentially ...

After 30 years of refinements, mud-pulse systems transmit data more quickly and more accurately, through increasingly deep wellbores. Operators are pushing telemetry systems to transmit real-time data ...
