At first glance, this agreement is surprising, given that our 5-fs pulse duration would be expected to introduce a roll-off at approximately 100 THz, with rapidly decreasing sensitivity at higher ...

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 ...

DSOs (digital oscilloscopes) offer a great many advantages over their analog equivalents but as they say, “There’s no such thing as a free lunch.” Digital scopes sample, digitize, and store waveforms ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

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 ...
