Block Scalar Multiplication(ADAU145x)
Scalar Multiplication is a block processing module which multiplies scalar values specified in a
table with the input block of samples.
Input Pins
| Name | Format [int/dec/float] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Input | decimal-audio | Input signal to the module |
Output Pins
| Name | Format [int/dec/float] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Output | decimal- audio | Output signal from the module |
Grow Algorithm
The module supports growth functionality, the number of channels to the module can be grown. Add is not supported.

Algorithm Description
This module multiplies the input block of samples with scalar values specified in the table
at their respective indexes. The size of the table will be equal to the block size set for the
schematic. Multiplication can be enabled or bypassed using the Enable/Bypass button present on the
cell.
Example
In the example shown below, block output of the DC block [1,1,1…,blocksize times] is multiplied by the scalar values in the table [1,2,3,…..,blocksize] at their respective indices.
On Clicking the bypass option, the scalar values are bypassed and the input signal is passed to the output
as is.
