Creating a boolean generator from a square wave source?

Hi audiolab,

The boolean logic in SigmaStudio is in 28.0 format, whereas the square wave is in 5.23, so you have to convert. The easiest way to do this is by using an AB in, CD out cell. I attached an example. If the 5 Hz sine signal is greater than zero, then the output of the logic cell is one (in 28.0 format), and the mux picks input channel 0. If the sine tone is less than zero, then the output of the logic cell is zero (in 28.0 format), and the mux picks input channel 1.

Hi Brett,

I have had a block similar to the above working in another project for some time now. For a new project I am looking at toggling back and forth between three values with a three-input index selectable mux. I have a "common" line, which we can assume corresponds to the mux input selected by decimal value 1. At a rate determined by the frequency of the square wave generator, I want to repetitively switch the mux inputs back and forth in the following manner:

1-0-1-2-1-0-1-2-1-0...

I have tried to get a decimal generator working in this manner using logic blocks, but have not had any luck.

Any suggestions?

Thanks!

audiolab1, how about using these cells to do the job?

Pulse generator

Toggle counter

Index lookup table

Index selectable multiplexer

You can hook them up like this:

Note that the table values are 1,0,1,2 as you requested.

I haven't had a chance to test this on the hardware, but I think it should work in your application.
