Design a low pass active filter that passes frequencies at 900 Hz and below and at these values the magnitude (in dB) of the transfer function is 20+-3(between 23 dB and 17 dB). The circuit's magnitude (in dB) of the transfer function at a frequency of 13.5 kHz or more will be less than -15dB.
Draw circuit and list its components
Determine the Corner frequencies, the Passband gain, and the Transfer function
