## Homework Statement

Write a report (of approximately 750 words) that discusses and compares

the design of each filter in terms of their performance, circuit topology,

application and any other relevant characteristics. You may for example

attempt to relate the choice of component values to the filters

performance.

## Homework Equations

[tex]f_c=\frac{1}{2{\pi}RC}[/tex]

## The Attempt at a Solution

The topology of the of the circuit is a first order high pass filter followed by a second order Sallen and key.

As the first part is an RC high pass buffered circuit, I believe the TF can be cascaded (multiplied).

I'm unsure how to work out the corner frequency

Do I work out each part of the circuits Fc?

or is there an overall equation for this circuit

The response of the overall circuit must be to do with the Q factor of the Sallen and key

All help is appreciated

Thanks
