2.2.1 Generate the Waveform for the Letters ‘S’
The waveform of the letters ‘S’ can be obtained by generating a waveform that contains the pattern for the letter and the two signals acting as masks and applying a logic function on them.
The operation mentioned above is: SS = M1 AND M2 AND S’
The truth table of the logic operation is presented in the table below:
| M1 | M2 | S’ | SS |
|---|---|---|---|
0 | 0 | 0 | 0 |
0 | 0 | 1 | 0 |
0 | 1 | 0 | 0 |
0 | 1 | 1 | 0 |
