aula 18 - Decodificadores

Today we will understand what decoders are and how to generate this type of combinational circuit. Thank you very much and a big hug! Note: when the CARD appears in the upper right corner (written LOOK IN THE DESCRIPTION) it means I made a small writing error and need to point it out here. This card appears when checking the answers of the BCD to 7-segment decoder. The Boolean expressions are correct, except for the letter "g", in which I used the XNOR symbol (coincidence) but it is actually an XOR (exclusive OR) gate. This is why I only said XOR when reading the answers. So when I say XOR in this part of the video, it is only for the output related to the LED 'g'. The other outputs of the display are with XNOR. I apologize for the confusion, it was a mistake when writing. I thank everyone who noticed this small error. In lesson 51 of the module, I show in detail again how to assemble the BCD to 7-segment decoder; the CARD will redirect you to this lesson. thanks.
