High cut off frequency

WebIn this study, we investigated the impact of intrinsic output conductance (goi) on the short-circuit current-gain cut-off frequency (fT) in InxGa1-xAs/In0.52Al0.48As quantum-well (QW) high-electron-mobility transistors. 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 … WebHigh-resolution black-and-white film is capable of resolving details on the film as small as 3 micrometers or smaller, thus its cutoff frequency is about 150 cycles/millimeter. So, the telescope's optical resolution is about twice that of high-resolution film, and a crisp, sharp picture would result (provided focus is perfect and atmospheric turbulence is at a minimum).

In electronics, cutoff frequency or corner frequency is the frequency either above or below which the power output of a circuit, such as a line, amplifier, or electronic filter has fallen to a given proportion of the power in the passband. Most frequently this proportion is one half the passband power, also referred to as the 3 dB point since a fall of 3 dB corresponds approximately to half power. As a voltage ratio this is a fall to of the passband voltage. Other ratios besides the 3 dB p… WebThe cutoff slope will be -40dB/decade, which may or may not be enough to meet your need. Another approach would be to use a switched capacitor filter with more poles, and change the clock frequency to change your cutoff.

H ( j ω c) = 1 1 2 + ω c 2 R 2 C 2 = 1 2 ⋅ H ( j 0) = 1 2 Solve it for ω c (cutoff angular frequency), you'll get 1 R C. Divide that by 2 π and you get the cutoff frequency f c.

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.
