Hey,
I've read some threats here about analog signal filtering. Most propose a first order filter. I've done some experiments with first order filters and experienced best results with cascading first order filters. Especially towards delay time of the filterd signal. It was better to cascade f.i. three filters with a moderate filter constant then to use a high filter constant on one filter.
I am not experienced in the theoretical principles of filters, I wondered if some people used more sophisticated filters (like Butterworth or so) and what their experiences were ?
Thanks.
