1 Filter Design Filtering in time (sampling) Filtering by amplitude (window discriminator) Frequency filtering Low Pass, High Pass, Band-pass, Notch filters Signal-to-noise ratio Error-correcting codes Aiming toward the Filter Quiz…

2 Reading: Handout on active filters, selected pages from Chpt 5 of Horowitz & Hill, The Art of Electronics (2nd Ed), Cambridge Univ Press (1989) Book itself on the 095 bookshelf…

3 The bandpass filter diagram is not complete: A unity gain voltage follower (UGVF) op amp is needed between the LP and HP filters to isolate the components in LP filter from interacting with components in the HP filter.

4 Low pass, high pass, active filters Ref mysite.mweb.co.za
