● Finite Impulse Response Filter Design

● Design Method Selection – FIR Windows Design – FIR Equiripple Design (Parks-McClellan)

● Lowpass, Highpass, Bandpass and Bandstop filters

● FIR filters can have up to 513 taps

● Following window functions are supported: Rectangular 4 Term Cosine Hanning (Hann) 4 Term Cosine with continuous 5th Derivative Hamming Minimum 4 Term Cosine Triangular Good 4 Term Blackman Harris Blackman Harris Flat Top Exact Blackman Kaiser 3 Term Cosine Dolph-Tschebyscheff 3 Term Cosine with Taylor continuous 3rd Derivative Minimum 3 Term Cosine Gaussian

● Reports show design details such as window coefficients and Impulse Response prior to multiplying by the window function

● Filters are designed for a maximum gain of 1 Infinite Impulse Response Filter Design

● Lowpass, Highpass, Bandpass and Bandstop Filters

● Filter orders up to 10 for Lowpass and Highpass Filters

● Filter orders up to 20 for Bandpass and Bandstop Filters

● Five Analog Prototype Filters are available: – Butterworth – Tschebyscheff – Inverse Tschebyscheff – Elliptic – Bessel

● Digital Transformations are performed by Bilinear Transformation Method

● Reports show design details such as all transformations from normalized lowpass filter to desired filter
