Question 1

Ten samples of a digital signal that is detected in the presence of noise are given below.The original
digital signal values are either equal to -1 or +1.Apply a threshold to the detected samples to form
the reconstructed digital data values.
Detected values: 0.8, 0.5, -1.1, -0.4, 1.3, 0.8, -0.7, -0.9, 1.1, -0.8

Answer 1

Apply a threshold equal to 0, halfway between -1 and +1.
The reconstructed data values: 1, 1, -1, -1, 1, 1, -1, -1, 1, -11
