Unwrap
5-483
Do not unwrap phase discontinuities between successive frames
When this parameter is cleared, the block unwraps each input’s channels
(the input channels are the columns of frame-based inputs and each
element of sample-based inputs). When this parameter is set, the block
unwraps each row of sample-based row vector inputs, and unwraps the
columns of all other inputs, where each input matrix or input vector is
treated as completely unrelated to the other input matrices or input
vectors. 1-D vector inputs are always treated as frame-based column
vectors. See “The Two Unwrap Modes” on page 5-475.
Tolerance
The jump size that the block recognizes as a true phase discontinuity. The
default is set to π (rather than a smaller value) to avoid altering legitimate
signal features. To increase the block’s sensitivity, set
Tolerance to a value
slightly less than π.
