signal
Input sequence.
The number of elements in
signal
must be greater than or equal to
decimating factor.
This input accepts the following data types:

Waveform

Waveform in complex doubleprecision, floatingpoint numbers

1D array of waveforms

1D array of waveforms in complex doubleprecision, floatingpoint numbers

1D array of doubleprecision, floatingpoint numbers

2D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint numbers

2D array of complex doubleprecision, floatingpoint numbers
decimating factor
The factor by which this node decimates the input sequence.
decimating factor
must be greater than zero. If
decimating factor
is greater than the number of elements in
signal
or less than or equal to zero, this node sets
decimated signal
to an empty array and returns an error.
Default:
1
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Many nodes provide an
error in
input and an
error out
output so that the node can respond to and communicate errors that occur while code is running. The value of
error in
specifies whether an error occurred before the node runs. Most nodes respond to values of
error in
in a standard, predictable way.
error in
does not contain an error

error in
contains an error



If no error occurred before the node runs, the node begins execution normally.
If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as
error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the
error in
value as
error out.

Default:
No error
averaging
A Boolean that determines the method this node uses to handle the data points in the input sequence.
True 
Each output point in
decimated signal
is the mean of the
decimating factor
input points.

False 
Keeps every
decimating factor
point from
signal.

Default:
False
decimated signal
Decimated sequence of the input sequence.
This output can return the following data types:

Waveform

Waveform in complex doubleprecision, floatingpoint numbers

1D array of waveforms

1D array of waveforms in complex doubleprecision, floatingpoint numbers

1D array of doubleprecision, floatingpoint numbers

2D array of doubleprecision, floatingpoint numbers

1D array of complex doubleprecision, floatingpoint numbers

2D array of complex doubleprecision, floatingpoint numbers
error out
Error information.
The node produces this output according to standard error behavior.

error in

error out
output so that the node can respond to and communicate errors that occur while code is running. The value of

Algorithm for SingleShot Decimation
If
Y
represents the output sequence
decimated signal, this node obtains the elements of the sequence
Y
using the following equation:
If
averaging?
is False,
${Y}_{i}={x}_{i*m}$
If
averaging?
is True,
${Y}_{i}=\frac{1}{m}\sum _{k=0}^{m1}{x}_{i*m+k}$
for
i
= 0, 1, 2, ...,
size
 1,
$\mathrm{size}=\lfloor \frac{n}{m}\rfloor $,
where

x
is
signal

n
is the number of elements in
signal

m
is
decimating factor

size
is the number of elements in the output sequence
decimated signal

$\lfloor \mathrm{.}\rfloor $
gives the largest integer less than or equal to the number
