CHAPTER 1

Truth table for the Logic Diagram of Fig. 4 – 9. ... Multilevel NAND Circuits. The NAND gate is a universal gate because any digital system can be implemented with it. Figure 4 – 10 shows the implementation of NOT, AND, and OR by NAND gates. ... The following truth shows the Even-Parity-Generator Table: Three-bit Message Parity Bit. x y z P ... ................
