ButterWorth Filter (1st & 2nd Order) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12341
Indian Lab Suppliers supplies the ButterWorth Filter (1st & 2nd Order) (Product ID: 12341) as part of its electronics engineering lab equipment range. It is a board for studying first- and second-order Butterworth low-pass and high-pass active filters.
Quick Answer
The board holds four op-amp filter circuits: first- and second-order low-pass filters with a 1 kHz upper cut-off, and first- and second-order high-pass filters with a 1 kHz lower cut-off, all designed for a pass-band gain of 2. A Butterworth response is maximally flat in the pass band; beyond cut-off it falls at 20 dB per decade for first order and 40 dB per decade for second order, which students confirm by plotting gain against frequency. A ±12 V DC, 50 mA IC-regulated supply is built in; a signal generator and oscilloscope are needed for the frequency-response plots.
