You are provided with two figures. Figure 1 is a 10 x 5 Programmable Array Logic (PAL)circuit whereas Figure 2 is a 5 x 3 Programmable Logic Array (PLA) circuit. You are required to write An ABEL code/expression for both circuits.

PAL: 10 Inputs (I1, I2, I3, I4, I5, I6, I7, I8, I9, I10) & 5 Outputs (O1, O2, O3, O4, O5).

PLA: 5 Inputs (O1, O2, O3, O4, O5) & 3 Outputs (X, Y, Z).

Output 100) Figure 1: Programmable Array Logic (PAL) 101 09 OLX Output Output Figure 2: Programmable Logic Array (PLA) Output 100) Figure 1: Programmable Array Logic (PAL) 101 09 OLX Output Output Figure 2: Programmable Logic Array (PLA)
