Visualization of Human eye as a low pass filter in MATLAB

Human visual system model https://en.wikipedia.org/wiki/Human_v... MATLAB CODE: clc clear all close all figure pause(2); hold on; n=0:0.001:10; x=0.5026*(n==0.523)+1*(n==1.577)+0.5*(n==2.618)+(-0.007037)*(n==3.143)+(-0.5008)*(n==3.665)+(-1)*(n==4.714)+(-0.4931)*(n==5.758)+(-0.0009265)*(n==6.2863)+0.5077*(n==6.805)+1*(n==7.852)+0.4992*(n==8.901)+0.00389*(n==9.424)+(-0.4973)*(n==9.949); stem(n,x); hold on; pause(3); t=0:0.001:10; x=sin(t); comet(t,x); plot(t,x,'b'); hold on; pause(3); t=0:0.001:10; x=sin(5*t); comet(t,x); plot(t,x,'m'); When we see the samples , we interpret them as the samples of lower frequency sinusoid. The eye does not see / reconstruct the higher frequency sinusoid between samples because the eye is basically a lowpass filter.
