Although the electromagnetic spectrum is a continuum, a strong distinction is typically drawn between electronics and optics. This distinction is due, in part, to the very different technologies used ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

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 ...

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 ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Radar is a remote sensing technique used to detect, locate, and analyze objects by emitting electromagnetic waves, more specifically microwaves, and measuring the time interval between the ...

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 ...
