Hi all
I have this quation and I can not understand it at all

Many thx

A filter circuit is required to pass frequencies between 100 Hz and 10 kHz with less than 1 dB error and to reject frequencies below 10 Hz by at least 30 dB and frequencies above 100 kHz by at least 40 dB. Draw a graph illustrating this functional description and identify the passband, stopbands and transition regions.

This question can be answered with a few internet searches

Try this

http://en.wikipedia.org/wiki/Band-pass_filter

and have a look at this website's tutorials on Filters - not just the one on bandpass filters but the whole lot so you can see how it all goes together .

The graph would be drawn with attenuation in dB's on the y axis and 6 decades of frequency on the x axis
