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 ...

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 ...

Measurement of average power in a 60Hz circuit (equivalent to V RMS × I RMS × cos(ø)) can be done by sampling the product of voltage and current and averaging. This requires four quadrant ...

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 ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...
