Active Filters
Product Code : JA-AET-1466
The active filters trainer is used to study the characteristics of op-amp active filters: a 1 kHz low-pass, a 100 Hz high-pass, a 100 Hz to 1 kHz band-pass and a 1 kHz notch filter. Four operational amplifier ICs and an internally connected ±12 V DC, 50 mA regulated supply are built in, and the cut-off slopes and impedances are listed for each filter (SKU JA-AET-1466).
