Problem 1: Let VTRUE be 9 V and let VFALSE be -3 V. Let TPWM be 0.5 second. What is TOFF to get an average output of 2.6 V? Enter your answer to the 3rd nearest decimal place in seconds.

PROBLEM-SOLVING: Topic: "Digital Logic" A Chemical plant needs a microprocessor-driven alarm system to warn of critical conditions in one of its chemical tanks. The tank has four (HIGH / LOW) switches that monitor: Temperature (T) Pressure (P) Fluid Level (L) Weight (W) You have to design a system that will notify the microprocessor to activate an alarm when any of the following conditions arise: High Fluid Level with High Temperature and High Pressure Low Fluid Level with High Temperature and High Weight Low Fluid Level with Low Temperature and High Pressure Low Fluid Level with High Temperature and Low Weight Note: Step 1: Create a truth table with appropriate input-output combinations according to the data given. Step 2: Since it has 'four input variables', draw a four-variable K-map (Karnaugh Map). After that, transfer the output logic in the truth table to the equivalent cells in the K-map. Get the simplified Boolean expressions using the K-map technique. Step 3: Construct the…
