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...
6. Low-pass filter calculator A Bode plot is used to calculate the crossover frequency and depict the associated spectrum for the RC low-pass filter circuit. For example, if we know the resistance and capacitance values in the circuit, we can compute the low-pass filter transfer function usi...

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 ...
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...
