|Designing a low frequency filter
||Designing a low-frequency filter with the following characteristics.
Supply is +5V and GND.
The filter should have a gain of -10 (inverting). (Gain in this context might sometimes be referred to as AC-gain)
The filter should have a bandwidth of 1kHz.
The filter should be able to drive a 100 Ohm resistor.
You should make a design with an opamp (try and select one) and back your findings wit...
