Design a 6th-order highpass FIR filter with a passband frequency of 75 kHz and a passband ripple of 0.2 dB. Specify a sample rate of 200 kHz. Compute the coefficients of the equivalent transfer function.
Digital filter, specified as a digitalFilter object. Use designfilt to generate a digital filter
based on frequency-response specifications.
Example: d =
designfilt('lowpassiir','FilterOrder',3,'HalfPowerFrequency',0.5)
specifies a third-order Butterworth filter with normalized 3 dB frequency 0.5π
rad/sample.
