3 Working with Signals
3-32
convert a frame-based signal to a sample-based signal is by using the Unbuffer
block. See the following sections for more information about these methods:
•“Buffering Sample-Based and Frame-Based Signals” on page 3-47
•“Unbuffering a Frame-Based Signal into a Sample-Based Signal” on
page 3-60
On occasion it may be desirable to change the frame status of a signal without
performing a buffering operation. You can do this by using the Frame Status
Conversion block in the Signal Attributes library.
The
Output signal parameter (or the signal at the optional Ref input port)
determines the frame status of the output If the frame status of the input
differs from the
Output signal setting, then the frame status is altered as
specified. If the frame status of the input is the same as that specified by the
Output signal parameter, then no change is made to the signal.
The block’s input and output port rates are the same, and because the block
does not make any sample rate accommodation, the sample rate of the signal
is generally not preserved under a change of frame status. (The exception to
this rule occurs when a sample-based signal is converted to a frame-based
signal with frame size 1, or vice versa.)
See the Frame Status Conversion block’s reference page for complete
information.
