At its core, we attempted to extract values of fT using a simplified small-signal model (SSM) of the HEMTs and to derive an analytical …

WebThe BJT Cutoff Frequency and Capacitance can be expressed in two ways, the common emitter cutofff frequency fαe, and. the common base cutoff frequency (fαb). f αe is the frequency at which the common emitter current gain (h fe ), falls to 0.707 x (mid-frequency h fe ). f αb is the frequency at which the common base current gain (h fb) falls ... WebConcerning the cut-off frequency, there's really not much of a difference between analog and digital filters. $3\textrm{ dB}$ is common, but any other value is fine, as long as you specify it and people know what you're talking about. In the case of the given filter, it's quite straightforward to compute any cut-off frequency.

When doing digital filter design you normally work with normalised frequency, which is just the actual frequency divided by the sample rate. So in your example where you want to specify a cut-off of 50 Hz at a sample rate of 500 Hz then you would specify this as a normalised frequency of 0.1. how to reset mysql xampp
