Signal Add
Click here to return to the Basic DSP page
There are three version of 'Signal Add' algorithm.
- Signal Add (Real Signals)
- 2 Channel Adder (Real Signals)
- Signal Add (Complex Signals)
Signal Add (Real Signals)
The Signal Adder block adds inputs together. No other modification of the signal is done.
Care must be taken to avoid clipping. If automatic gain reduction is needed to avoid clipping, use the Signal Merger block.
2 Channel Signal Add (Real Signals)
This algorithm adds the 2 signal and produces an real signal. When the algorithm is grown it takes multiple pairs of input signal and adds each pair to produce an output signal.
Input Pins
| Name | Format [int/dec] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Operand 1 | any | Input signal 1 |
| Pin 1: Operand 2 | any | Input signal 2 |
Output Pins
| Name | Format [int/dec] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Output Signal | any | Output signal |
Grow Algorithm
Module can be grown 16 times. For each growth input is grown by 2 and output by 1.
Supported DSPs
ADAU145x
Signal Add (Complex Signals)
This algorithm adds the complex signals. (All real parts are summed together and all imaginary parts are summed together)This is a block based module.
Input Pins
| Name | Format [int/dec] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Operand 1 | complex | Input complex signal 1 |
| Pin 1: Operand 2 | complex | Input Complex signal 2 |
Output Pins
| Name | Format [int/dec] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: Output Signal | Complex | Complex output signal |
Grow Algorithm
input pins can be grown up to 8 channels.
Supported DSPs
ADAU145x (Block Schematic only)
Example Usage
This can be used to add two signals FFT's result as shown below.
