Here is my code:

n = 0:49; % These are the time indices

input = 7*cos(2*pi*0.125*n+pi/3);

input_a = 2*input;

input_b = 8*cos(2*pi*0.25*n);

input_c = input_a + input_b;

b = [5, -5]; % The filter coefficients

y = conv(b,input); % The output signal

y_a = conv(b,input_a);

y_b = conv(b,input_b);

y_c = conv(b,input_c);

subplot(2,2,1);

plot(input, 'b*-'); % Plot the input as a blue line

hold on;

plot(y, 'r.-'); % Plot the output as a red line

hold on;

xlabel('Time'); % Label x axis

ylabel('Amplitude'); % Label y axis

subplot(2,2,2);

plot(input_a, 'b*-'); % Plot the input as a blue line

hold on;

plot(y_a, 'r.-'); % Plot the output as a red line

hold on;

xlabel('Time'); % Label x axis

ylabel('Amplitude'); % Label y axis

subplot(2,2,3);

plot(input_b, 'b*-'); % Plot the input as a blue line

hold on;

plot(y_b, 'r.-'); % Plot the output as a red line

hold on;

xlabel('Time'); % Label x axis

ylabel('Amplitude'); % Label y axis

subplot(2,2,4);

plot(input_c, 'b*-'); % Plot the input as a blue line

hold on;

plot(y_c, 'r.-'); % Plot the output as a red line

hold on;

xlabel('Time'); % Label x axis

ylabel('Amplitude'); % Label y axis

How do i work the phase difference between the output of y_b to the input and the phase difference of y_c to the input.
