Low pass filter

[Jantz]

If i had a sawtooth function of 1KHz and peak amplitude of 10 volts, at what frequency will this signal pass through a low pass filter with 3.5kHz?

 

[Harald Kapp]

At any frequency - with varying degrees of distortion. You do the math.

You forgot to say any details about the lowpass filter. A simple single order RC? Then it cuts the harmonics gradually.
If its cutoff frequency is 3.5kHz then it noticeably cuts 3.5k/5= 700Hz and higher.

That's everything i had for the question. When its need to be divided by 5?

Look at a graph in Google of the frequency response of a simple single-order RC lowpass filter. It begins dropping at 1/5th of the -3dB cutoff frequency.

I see....And ya the cutoff frequency is 3.5khz sorry i didn't notice it...Thanks btw can i pm u?
