Description: |
The Signal Pre-emphasis component applies a multiplier delayed by one sample on to the incoming array of type double digital signal. It is fairly common to consider pre-emphasis as a means to boost only the signal's high-frequency components, while leaving the low-frequency components in their original state. In general, the operation can be described as: s2(n) = s(n) - a*s(n - 1). Here, a is the pre-multiplier. By default this value is set at 0.95. This can be changed in the properties dialog box for the component. |
