In some respects, the two techniques are similar since they are both analog sampled data filters which make use of charge storage on capacitors. However, in most other aspects, they are fund a mentally very different since CD transversal filters use only transfer function zeros to shape the frequency response, whereas the switched capacitor ladders are recursive filters which make use of both poles and zeros. For some application a transversal, all zero filter must be used, such as when true linear phase is required or in matched filtering. On the other hand, a very narrow bandpass filter can be realized using a simple pair of high Q poles, which is much more efficient than using a CCD transversal filter which would require many zeros and therefore many CCD stages for a narrow passband response. 1- LM741 is used as an OPAMP. 2- All components should be SMD form. Additionally, resistors and capacitors are 0805 type. 3- Connections of components should be used as copper foliated. 4- PCB's dimension should be 8 cm x 4 cm (9 cm x 5 cm optional).
