Sampling and Reconstruction

• Once $x(t)$ is sampled to produce $x(n)$, time scale information is lost.

• $x(n)$ may represent a number of possible waveforms.

  
  
  
  

  

• Reconstructing at half the sampling rate ($F_s/2$) will double the time between samples ($2/F_s$), making the sinusoid twice as long and halving the frequency.
