Convolutional (Encoder & Decoder)

Convolutional (Encoder & Decoder)
Scientech 2122A & 2122B

Product Description

Scientech TechBooks are compact and user friendly learning platforms to provide a modern, portable, comprehensive and practical way to learn Technology. Each TechBook is provided with detailed Multimedia learning material which covers basic theory, step by step procedure to conduct the experiment and other useful information.

Scientech TechBooks 2122A and 2122B Convolution encoder and decoder are designed to provide Conceptual and Step by Step understanding of Convolution codes. Block  wise modular organization of circuit functions with Code tree ,State and Trellis Diagram makes it easy to understand,  the process of encoding and decoding. Additional on board redundant bit generator is provided so that user can insert error to generated code and decode error free data.
