WebFeb 3, 2024 · A Don’t Care cell can be represented by a cross (X) or minus (-) or phi (Φ) in K-Maps representing an invalid combination. For example, in the Excess-3 code system, the states 0000, 0001, 0010, 1101, 1110, and 1111 are invalid or unspecified. These states are called don’t cares. WebOften, the SOP and POS forms of equations looped from K-maps that contain don’t cares are not algebraically equal (although they would perform identically in the circuit). The following examples in Fig. 2 illustrate the use of don’t cares in K-maps. Figure 2. Looping K-Maps …

WebK-map group rules Not any group of adjacent ones can form a valid group. For example, you might have been tempted to group together the three 1's on the bottom row of the previous example. But we can't do that, because there wouldn't be a single AND term that would correspond to those three 1's. WebHere is a truth table for a four-input logic circuit: If we translate this truth table into a Karnaugh map, we obtain the following result: Note how the only 1’s in the map all exist on the same row: If you look at the input variables (A, B, C, and D), you should notice that only two of them are constant for each of the “1” conditions on ... katherine jenkins silence is all you know
