Method for the calculation of the coefficients of a polyphase FIR filter Object of the invention is a method for the calculation of coefficients of a FIR filter capable of simultaneously performing the two functions of band pass and equalization of the sinc(x) distortion generated by the DAC in...
The effect of zero insertion is illustrated in Figure 7.5, where the magnitude function ∣H0(ejω)∣ of an ideal highpass filter is shown together with the function ∣H(ejω)∣ resulting from setting D = 5. The D-fold repetition of the filter transfer function attenuates not only the ...

a surrogate neural network model was used to design a microstrip power divider and a low-pass filter (LPF). The suggested technique improves the performance and frequency response of a wide range of microwave devices. Their efficient design is a result of using the surrogate model of the propos...
If we choose a Chebyshev filter for the design, the normalized analog filter is exactly the same third-order Chebyshev lowpass filter obtained in Example 4.3. The normalized analog lowpass filter has a transfer function Ha(s)=0.3269(s+0.3689)(s2+0.3688s+0.8861) ...
All motion capture data were labeled and gapfilled in Vicon Nexus and exported to Matlab to be low-pass filtered at 10 Hz with a 4th order Butterworth filter. Velocity data were obtained from the time derivative of marker position data. Force data were also low-pass filtered at 10 Hz with...
