For the transistor, assume that = 100, V BEON = 0.7V and V CESAT = 0.2V. Let logic 1 be 5.0V and logic 0 be 0.2V. Fill in a truth table for V o vs. V 1 and V 2 using the actual voltage values. What type of logic gate does this circuit represent. Assume a threshold voltage of 2.5v. 9.2 Consider the circuit shown below. For the transistor, assume that = 100, V BEON = 0.7V and V CESAT = 0.2V. Let logic 1 be 5.0V and logic 0 be 0.2V. Fill in a truth table for V o vs. V 1 V 2 V 1 1 k 1 k 1 k V o V CC = 5V 207 207 Digital Electronics and V 2 using the actual voltage values. What type of logic gate does this circuit represent. Assume a threshold voltage of 2.5v. 9.3 For the circuit shown below, use V DON = 0.7V. For a logic 1 input use 5v. For a logic 0 input use 0v. A logic 1 out- put is obtained if the voltage is greater than 3v. A logic 0 output is obtained if the voltage is lower than 2v. Determine the logic function of the circuit shown below. Show a truth table which includes input and output voltages and be sure to justify your results. 9.4 For the circuit shown below, use V DON = 0.7V. For a logic 1 input use 5v. For a logic 0 input use 0v. A logic 1 out- put is obtained if the voltage is greater than 3v. A logic 0 output is obtained if the voltage is lower than 2v.
