对比纯微分环节和经典微分器的Bode Plot,我们发现在低频段他们的幅频和相频特性是相近的,但是达到cutoff frequency之后,微分器的输出幅值变化就不大明显了,维持在最后的常值。我们可以通过传递函数看出,当s很大时,幅值就是常数 20{{\log }_{10}}(1/T) \[\underset{\omega \to \infty }{\mathop{\lim }...
Figure 11.5. Bode diagram of the R-C lowpass with R=10kΩ and C=0.1μF. The cutoff frequency is f0=1/(2πRC)=159Hz, indicated by the vertical dotted line. The asymptotes are drawn as gray dashed lines. The magnitude asymptote for ω≫1/RC has a slope of −20 dB/decade. ...

sigA[] is original input signal (also input to LowPassFilter) sigB[] is the output of LowPassFilter with Cutoff freq. of 10Hz and sampling frequency of 100Hz. Now, I'd like to verify sigB[] whether sigA is being properly filtered through LPF or not. Is there anyway, that I can ...
There is also the time domain view. Networks that are frequency sensitive also have time domain response which depends on the exponentials where the frequency response does not show this information unless you sweep over a wide range of frequencies. You may get away with just sweeping the freque...
