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.

Figure 1. Waveform for the Letters S

The operation mentioned above is: SS = M1 AND M2 AND S’

The truth table of the logic operation is presented in the table below:
