2. Encoders Method for putting information into a usable form. Uses:
Convert a combination of active lines into a code
Compression
Audio/Video digital formats
Telecommunications
The way we can use it, related to the class, is to classify a group of active lines into a single binary representation

3. Decoders The reverse operation of an encoder.
Frees the information from some coded form.
We can take some sort of coded signal and cause it to make active lines as its output

4. Related to Project We have a seven segment LED.
Which of these circuits do we use?
OK, now let’s design

5. Project So we have the full set of terms for part fo the project now.
However, what if you want to implement it in hardware?
On your own, use your minimization techniques learned in class to simplify the expressions.
We cover the cases of 0-9 in our design, but we can actually cover the hexadecimal cases too, A-F.
