Math component

Component to combine together two DSP buffers into one an index at a time. Functions include: Add, Average, Difference, Max, Min, Subtract

Detailed description

No detailed description exists yet for this component

Examples

Here is a example file which generates a sine wave and a triangle wave and then uses the DSP sum component to merge together the two signals. FC6 Icon.png DSPSum Here is the kind of waveform you can expect to see using the scope window when adding the two signals together.

DSPSum.jpg


Here is the kind of waveform you can expect to see using the scope window when subtracting the two readings.

DSPSum3.jpg


Here is the kind of waveform you can expect to see using the scope window when taking the maximum of the two signals.

DSPSum2.jpg


Here is the kind of waveform you can expect to see using the scope window when taking the minimum of the two signals.

DSPSum4.jpg


Here is the kind of waveform you can expect to see using the scope window when taking the average between the two signals.

DSPSum5.jpg


Here is the kind of waveform you can expect to see using the scope window when taking the difference between the two signals.
