Donwsampling and Upsampling ADAU1467
Hello all, I am trying to do a simple factor 4 downsample and upsample in sigma studio. I have made the FIR butterword filter for the antialiasing. however, in the output I am encountering aliasing in

Decimation - Output sampling rate
Hi, I have adau1452 sigmaDSP on an A2B chain and this dsp streams data to the host (SC589-SAM). The adau1452 receive samples from an accelerometer and is programmed with a decimation block via sigma s

UpSampling algorithm version 1.02 broken
I have just tried the latest version (1.02) of the Upsampling algorithm with SigmaStudio 4.6 and an ADAU1452. I am running at 96kHz sample rate and downsampling 16x, then Upsampling, with no filtering

[ADAU145x] Downsampling to arbitrary value
Hello folks, I'm trying to downsample a signal to a sampling rate of 10Hz on an ADAU1452. The main sampling rate is 48000Hz. My problem is that the downsampling block doesn't allows a downsampling rat

Downsampling/Upsampling blocks up to 64
Hello, I have a specific processing structure where I need to work at 750Hz (48k stream downsampled by 64). But because the downsampling/upsampling blocks are maximum 16, I do 2 downsampling/upsamplin

SigmaStudio: Can't save/reload design with heirarchy blocks using downsampling ADAU1452
I have found a troublesome bug in Sigma Studio. I am working on a large design for the ADAU1452, and the sampling rate is 192kHz. There are some control blocks that do not need to run at this rate. Th

ADAU1701: ADC_RES value, Synchronous Multiplexer
I am working with the ADAU1701 eval kit and have to say this is a truly great product! Two questions: - the datasheet describes how to change ADC0/1 resistor values to alter input sensitivity, but is
