Estimates the Chebyshev filter order.
The type of filter that this node estimates.
Estimates a lowpass filter.
Estimates a highpass filter.
Estimates a bandpass filter.
Estimates a bandstop filter.
Band edge frequencies of the filter, in Hz.
First passband edge frequency in Hz.
First stopband edge frequency in Hz.
Second passband edge frequency in Hz. The node ignores this input for lowpass and highpass filters.
Second stopband edge frequency, in Hz. The node ignores this input for lowpass and highpass filters.
Ripple level in the passband and stopband of the filter.
Ripple level in the passband.
Ripple level in the stopband.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The sampling frequency in Hz.
This value must be greater than zero.
Default: 1.0 Hz, which is the normalized sampling frequency
Minimum order value that the filter requires to meet the specifications you set.
Low cutoff frequency. The cutoff frequency corresponds to the edge frequency of the passband.
High cutoff frequency. The cutoff frequency corresponds to the edge frequency of the passband.
Error information. The node produces this output according to standard error behavior.
Ripple level in the passband, in decibels.
This node uses the following equations to estimate the order of a Chebyshev I filter:
The following table lists the equations for calculating and for different types of filters:
where the various values equal as follows:
