So what is your question actually? What did you try and is not working for you?

Simply used your info and coded in matlab
you have now here the right half of the plot , if you need both negative and positive frequency plot (as in your picture), simply mirror the data
Ts = 1;
f = linspace(0,16/(2*Ts),500); % normalized freq vector
s = 1i*(2*pi*f); % s = j*omega
G = (1-exp(-s*Ts))./(s*Ts);
plot(f,abs(G));
xlabel('Normalized Frequency (k/Ts)');
ylabel('|G|');
