Matlab Simulink Bit Extraction

I am attempting to use Matlab Simulink to quantize an analog signal and represent each of the quantization level values in binary format. I think I have this part accomplished using the attached Simulink model. I would now like to extract the first 3 bits for each of the binary representations in my time series and place them in their own 'channel' for further processing. I have been trying to use the Bit Extract block, however whenever I try to extract anything but the full range of bits, it fails. Any support would be greatly appreciated! Thank you.

Remove the "Integer to Bit Converter" block.

Hi, thank you for the response. It seems to work when I choose to display the value with the display block (although it doesn't show the entire time series), but when I write to the workspace it stores an integer value?

Basically what I would like to do is the following:

• Quantize an input sine wave
• Represent quantization level value in binary format. (e.g. For sine wave max value V_max = 5 => 00000101 (8-bit))
• Separate the bits into different channels. (e.g. Channel 1: 000 (first 3 bits) Channel 2: 00101 (rest of bits))
