Low Pass Bessel Filter LHBF-48X npi electronic GmbH
The LHBF-48X is an amplifier and low-pass filter designed for precise processing of small bio-electric signals. Equipped with a differential input stage with AC/0/DC switch, it provides adjustable amplification from 1 to 1000 without distortion. Its 8-pole Bessel filter provides effective low-pass filtering with a wide range of selectable frequencies, and additional options include a high-pass filter and a 50/60 Hz notch filter. Compact and reliable, it is ideal for applications requiring fine analysis of biological signals.
