WebSep 6, 2013 · One low-pass filter required only seven coefficients. Another needed 44. That number arose from a filter with a 1,500Hz pass-band cutoff frequency and a 2,000Hz stop-band cutoff frequency at -80dB. That's a sharp filter that's difficult to create with op-amps and passive components. The coefficients appear in a list with 18-digit resolution. fla job searchWebHigh-Pass, Band-Pass and Band-Reject Filters; Filter Classification; 15: Moving Average Filters.
