relationship between a frequency, frequency rate and time for good graph and good sound

function Sound_and_Draw_Signal_Over_Time( frequency, intensity, time )

%UNTITLED2 Summary of this function goes here %Detailed explanation goes here

fs = 80 * frequency;

%fs = 8000;

%%% TRY THIS Sound_and_Draw_Signal_Over_Time( 100, 5, 5 )

%%% to make this function work very well, I need to know

%%% what is the good relationship between a frequency and

%%% its corresponding frequency rate

t = 0:(1/fs): time;

y = intensity * sin (2 * pi * frequency * t);

figure

plot(fs*t(1:frequency),y(1:frequency));

title(['Signal of ', num2str(frequency) ,' Hz frequency']);

xlabel('time (milliseconds)')

ylabel('amplitude');

sound(y, fs);

% The Over sampling rate will be in good range if you call this

% function I just wrote.

function [Over_Sam_Rate] = F_frequency(frequency)

     if (frequency >= 20 && frequency <=2000)
         Over_Sam_Rate = 50;
     elseif (frequency > 2000 && frequency <=20000)
         Over_Sam_Rate = 10;
     end
