Sample Rates and Frame Rates
3-27
•Buffer adds duplicate samples to a sequence when the Buffer overlap
parameter, L, is set to a nonzero value. The output frame period is related to
the input sample period by
where M
o
is the output frame size specified by the Buffer size parameter. As
a result, the new output sample period is
•Delay Line adds duplicate samples to the sequence when the
Delay line size
parameter, M
o
, is greater than 1. The output and input frame periods are the
same, T
fo
=T
fi
=T
si
, and the new output sample period is
•Variable Selector can remove, add, and/or rearrange samples in the input
frame when
Select is set to Rows. The output and input frame periods are
the same, T
fo
=T
fi
, and the new output sample period is
where M
o
is the length of the block’s output, determined by the Elements
vector.
•Zero Pad adds samples to the sequence by appending zeros to each frame
when
Zero pad along is set to Columns. The output and input frame periods
are the same, T
fo
=T
fi
, and the new output sample period is
where M
o
is the length of the block’s output, determined by the Number of
output rows
parameter.
In all of these cases, the sample period of the output sequence is not equal to
the sample period of the input sequence.
