set_dndt_k

Set the value of the dn/dt filter coefficient for engine acceleration measurement in CyFlex.

Enter:

set_dndt_k <value> [units]

Where:

value	Specify the numerical value for the filter coefficient (0.0 to less than 1.0), frequency cutoff in Hz, or time constant in seconds.
units	Optional. Specify ‘hz’ for frequency or ‘sec’ for time constant.

Example:

set_dndt_k 0.10
specifies recursive filter coeff

set_dndt_k .5[ hz ]
specifies cutoff frequency

set_dndt_k .1[ sec ]
specifies time constant

Notes:

The program rejects values outside the valid range for the filter coefficient and calculates equivalent frequency and time constant based on input.
