Low-Frequency Filter Based on Analog Signal Processor Technology
Anadigm has introduced AnadigmFilter1, the first in a family of chipsets using its dynamically programmable dpASP and a state machine. This dynamically programmable ASP incorporates a universal analog filter architecture that provides the designer with frequency options from DC to 600 kHz, using a 6th order filter. Low pass, band pass, high pass or band stop circuits can be quickly implemented, without the usual digital-to-analog conversions or writing DSP or microprocessor programming code. The designer simply selects from the comprehensive library of pre-sets. The on-board filters can be selected to emulate Butterworth, Bessel, Chebyshev and inverse Chebyshev filter approximations.
