analoge to digital

i want to convert this analoge signal s = sin(2*pi*300*t)+2*sin(2*pi*600*t); to digital signal (pulses) could you please send me the command !

Please explain the desired format of the output. Of course even your "s" is a digital signal, because it is stored in the memory of a digital computer.

Do you want a representation e.g. by 16 bit integers sampled at 11KHz without a lowpass filter??

t = .01;

Fc = 10000; Fs = 80000;

t = [0:1/Fs:0.01]';

s = sin(2*pi*300*t)+2*sin(2*pi*600*t); % Original signal

[num,den] = butter(10,Fc*2/Fs); % Lowpass filter

y1 = ammod(s,Fc,Fs); % Modulate.

s1 = amdemod(y1,Fc,Fs,0,0,num,den); % Demodulate.

i want to convert this code into ask digital modulation
