I'm doing a lowpass fir equripple filter in matlab using simulink. My sine sources are 62.83 rads, 125.66 rads, 92.74 rads. In simulink how do you set it up to remove aliasing? By the way I'm sampling each sin wave at 1/50. Thank you. Also does normalizing remove aliasing? I'm very confused by the concept. Below are my block parameters.
