Check shifted input ( x[n-n_0] ).

Analog transfer function ( H(s) = \frac\omega_cs + \omega_c ) → impulse response ( h(t) = \omega_c e^-\omega_c t u(t) ) → sample: ( h[n] = \omega_c T_s e^-\omega_c n T_s u[n] ) → ( H(z) = \frac\omega_c T_s1 - e^-\omega_c T_s z^-1 ). Substitute numerical values. Apply windowing functions (e
