a. For the active filter circuit shown below, determine an expression for function in terms of R,, R, and C. R,

In Chapter 4, we used the time constant to characterize first-order RC circuits. Find the relationship between the half-power frequency and the time constant.

Input signals that have high voltage noise that must be filtered cannot be immediately buffered because the buffer power supply voltages are often lower than the voltages present in the noise.  With this in mind there are two circuits we have demonstrated that can work in this scenario. If you have a high impedance source, is it better to use an RC lowpass filter followed by a non-inverting amplifier, or to use an active lowpass filter design (both pictured below) and why?
