Compute Corrected Cutoff Frequency for Filter

Description

This function computes the corrected cutoff frequency for a lowpass or highpass filter using the correction factor by David A. Winter. For highpass filters, Robertson's high-pass modification is applied.

Usage

compute_cutoff_correction(
  filter_passes = 2,
  cutoff_frequency = 20,
  sampling_frequency = 200,
  type = "lowpass"
)

Arguments

filter_passes	Integer. The number of passes of the filter. Default is 2.
cutoff_frequency	Numeric. The cutoff frequency in Hz. Default is 6 for lowpass.
sampling_frequency	Numeric. The sampling frequency in Hz. Default is 200.
type	Character. The type of filter. Must be either "lowpass" or "highpass". Default is "lowpass".

Value

Numeric. The corrected cutoff frequency in Hz.
