I was running a simulation using De-modulator placeholder to simulate DTMF but I received error message that the receiver expecting signal type real but is being drive by signal type complex. Please any suggestion.
MATLAB: Complex signal mismatch

This block can be configured with a signal as the real part, and with the constant 0 as the imaginary part.
Try this
clc; % Clear the command window.
close all; % Close all figures (except those of imtool.)
clear; % Erase all existing variables. Or clearvars if you want.
workspace; % Make sure the workspace panel is showing.
format long g;format compact;fontSize = 20;t = linspace(0, 2*pi, 90);j = sqrt(-1);complexSignal = cos(t) + j*sin (t)% Get the real component and plot it on the x axis
x = real(complexSignal);y = imag(complexSignal);plot(x, y, 'bo-', 'LineWidth', 2);grid on;title('Plot of cos(t) + j*sin (t)', 'Fontsize', fontSize);xlabel('Real Component', 'Fontsize', fontSize);ylabel('Imaginary Component', 'Fontsize', fontSize);axis square;% Enlarge figure to full screen.
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);
