What I wrote on my Exam (and how many points I got)

The sampling theorem states that for a signal x(t) to be uniquely reconstructed, its X(jw) = 0 when |w| > wm, and the sampling frequency, ws, must be greater than 2wm


I got a 7/10 on this because I did not say what it is being reconstructed from. Also I used w because I did not know how to type omega in this file.


My Definition:


A signal can be recovered from sampling if-

         -The Signal is bandlimited and the Sample Frequency ($ \omega_s $) is greater than $ 2\omega_{max} $  (maximum frequency)
 
                        
                      <img alt="tex:\omega_{s}>2\omega_{max}" />


          Recieved 9/10 Points because it is not clear if I meant <img alt="tex:2\omega_{max}"/> or <img alt="tex:\omega_{max}"/> is the maximum       
          frequency
