Digital oscilloscopes are normally operated in real-time acquisition mode, where the analog input is sampled and digitized at a user-selected sampling rate and written continuously into the ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...

Mechanical resonance is a pervasive problem in servosystems. Most resonance problems are caused by compliance of powertransmission components. Standard servocontrol laws are structured for rigidly ...
