VOLTAGE CONTROLLED OSCILLATOR RESET PHASE

Thanks, Bob

I have performed this experiment and other anchor but the result it is always the same

Thanks Wilfrido,

if it is possible when the problem will be resolved told us

Piero

Hello Piero,

The problem you're experiencing can be duplicated by including the VCO Reset Phase in even the simplest project, shown below -- so apparently, something is wrong with the algorithm itself in SigmaStudio 3.9

I attached the project to assist ADI with troubleshooting this issue.

Best Regards,

Bob

Thanks piero and Bob.

This issue has been addressed, and now fixed. This fix will be available on the next beta Release.

Wilfrido.

Hi to everybody,

can someone explain that function is this and her operation? in the help doesn't exist

Thanks

Piero

Hello Piero,

The Synchronous Multiplexer appeared several SigmaStudio revisions ago, shortly after a customer asked about such a block at: https://ez.analog.com/message/72156#72156

It selects its inputs sequentially at the sample rate (each new sample comes from the next input). In its present form, it switches between its 4 inputs, starting over every four samples.

What can we do with it? The circuit below uses two synchronous multiplexers -- one makes a fs/4 clock, the other time-division multiplexes a delay to produce a 4x longer delay at 1/4 the sample rate. The result is an arena-sized echo effect which is otherwise not possible in a ADAU1701. Listen to a voice podcast through it, it sounds like they're in a cave.

Best regards,

Bob

Thanks Bob,

You are always kind

Piero
