那么当我们取一个 RC 电路电容部分的电压就能获得低通滤波(lowpass filter),而如果取电阻部分的电压就会获得高通滤波(highpass filter)。二阶电路更加有意思,如果取 RLC 电路的电容,我们依然会获得 lowpass filter 但是因为二阶衰减更加强烈所以获得的带宽更加窄。而如果取电感部分则获得 highpass filter。更加有意思...
The accompanying image shows the bode plot of the active low-pass filter. The gain in the pass band is –R1/R2 and the stop band drops off at -20 dB/decade (or −6 dB/octave). This is essentially a first-order filter. The closed-loop gain of the filter from the effect of the...
Thelow pass filter bode plotis shown below. Generally, the frequency response of a low pass filter is signified with the help of a Bode plot, & this filter is distinguished with its cut-off frequency as well as the rate of frequency roll off Low Pass Filter Using Op Amp Op-Amps oroper...
RC Low Pass Filter - Frequency and Bode Plot Calculator This tool calculates the crossover frequency for a RC low pass filter. In addition, it graphs the bode plot for magnitude in decibels and the phase in radians. The graph is unable to plot below 1Hz at the moment. The output ...

Let's illustrate a low-pass filter's frequency response (a fancy word for how a filter amplifies or dampens signals of certain frequencies). Take a look at the typical Bode plot for a low-pass filter below:The Bode plot (frequency response) of a low-pass filter. The blue line represent...
The typical graph of output-to-input voltage ratio (voviindecibels)(voviindecibels) plotted versus input frequency (f) for a low-pass filter is shown in Figure 2(a). This is the filter gain/frequency response graph (Bode plot). The output remains substantially equal to the input ...
