This paper presents design of low-pass and high-pass standard filter using Lattice Wave Digital Filter (LWDF). Standard filters like Butterworth, Chebyshev, Inverse Chebyshev, and Cauer Type I are reconstructed using LWDF coefficients and then the performance of every filter is compared. Results show that Cauer Type I Filter reconstructed using LWDF coefficients shows better filtering specifications than any other standard filter. In both Low-pass filter (LPF) and High-pass filter (HPF), Cauer Type I filter gives narrow transition width with constant stop-band attenuation which are favourable conditions for filtering process.
