E-Blocks Voice Codec Board US$35.50

EB032
E-Blocks Voice Codec Board


This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.

  • PCM CODEC
  • 13-bit linear signal processing
  • Pre and post filters
  • This audio coder-decoder board allows you to investigate digital signal processing systems that use audio. The EB032 is designed to incorporate Codec technology, and is capable of compressing and decompressing data. It features a Freescale MC145483 linear 13-bit PCM Codec filter with Two's Complement data format. The device performs the voice digitization and reconstruction as well as the band limiting and smoothing required for the voice coding in digital communication systems.

    Voice Codec E-Block Features

    • Works with the Bluetooth E-Block
    • Sockets for audio in and out
    • Volume control for both channels
    • Built-in high-pass audio filter
    Note that this E-block is for 3.3V systems only.

    E-Blocks Overview

    E-Blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-Block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system.

    E-Blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems.

    Each E-Block has one or more 9-way D-type connectors that provide up to eight input/output lines and a ground line. These D-type connectors allow connection between E-Blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-Blocks that need it.

    Processing E-Blocks based on PIC, dsPIC, ARM or AVR microcontrollers, Altera CPLDs, Arduino or Raspberry Pi control the whole E-Blocks system. Processing E-Blocks provide up to five input/output ports with up to eight lines per port.

    Please see the E-Blocks Category for a list of available components. For more details on E-Blocks, see the E-Blocks User Guide (in English, French, German and Spanish) or watch the Introduction to E-Blocks video.
