hi, how to write matlab code for RC 1st order low pass filter??
i saw many matlab codes from internet , like butterworth, chebychev...
but don't have the one for RC low pass filter??
pls advice how to do it? i was stuck in RC filter (...)

Guys i need to design these 2 filters
i mean to calculate the values of R and C
the 2nd order low pass filter is having frequency of 10Hz and 10KHZ respcetively, and the 1st order high pass filter is having 0.15HZ (...)

hey there... i've got question regarding 1st order butterworth filter...
i'm using Multisim software..
design a first order Butterworth low pass filter with cut-off frequency fo = 20 kHz and the gain K = 1. You will need to simulate the (...)

what is the relationship between integrators and low pass filters?
can we say integrators are the basis of low pass filters?
if i designed a integrator, how can i design a low pass filter based on it?? (...)

Would you let me know how to design high frequency limiter?
Added after 40 minutes:
May I use the rail to rail power supply as voltage limiter since the output voltage only can rearch power supply.
if the power supply is +4V to to -4V, the output only can rearch +-4V.

Forget the given formula for Fo. That's applicable for a 1st order lowpass only.
Here you have a second order active filter, which has to be calculated according to the rules that apply to an opamp with feedback. I assume you are familiar with opamp circuits.
When you compare the result (2nd (...)

I design the 1st order high pass filter for the with cutoff frequency 100 HZ and gain 100. My filter passes all the frequencies above 100 hz but when frequency goes above 1.3 Khz output goes in attenuation.Its tried every thing to increase the attenuation but (...)

Best low sensitivity high Q BPF is Salen & Keys design. Here is an integrated solution you can copy.
What you have is a LPF and a HPF , each is a 1st order filter, cascaded becomes a 2nd order..
A tuned 2nd order is better. and higher order permit (...)

Hey guys. Hope everyone is doing great.
I'm supposed to design a 3rd order Butterworth low-pass filter and so I combined 1st order and 2nd order Butterworth low-pass. That's what I need to do right? And so I did but (...)

In addition, I don't understand why you set the gain to a rather low value of 0.18. It's an independent parmeter of the MFB, I would usually start with a gain of 1, unless other parameters are required.
According to your bandpass design method, you'll face an additional gain reduction by cascading both filters.

can someone tell me why...
-we need inverting amplifer?why cant we jus amplify the signal during differential ampifier then pass to BPF filter out the noise then ok de
You don't need an inverting amplifier, it depends on the design.
