Prototypes of the band-pass filter (P-AXIS-00848)

P-AXIS-00848

Prototypes for the band-pass filter

Description

This parameter can affect the basic form and response of a band-pass filter The following prototypes are available:

  • Critically damped
    • Advantages: Highly stable broadband response with minimum oscillations.
    • Disadvantages: Low selectivity of centre frequency
  • Butterworth
    • Advantages: Excellent selectivity and steep edges
    • Disadvantages: Greater phase delay
  • Bessel
    • Advantages: Best phase accuracy and good time response
    • Disadvantages: Low selectivity of centre frequency
