Lab 1: Digital Logic GatesJacob PantaloneECEN 248 – 503 TA: Ye Wang February 4th, 2016Objectives:In this lab, I will work to analyze and understand the behavior of logic gates and the functions of each type of gate.Design:An HP6236B DC power supply is wired to the Vcc pin and the GND pin on the corresponding logic gate. A multimeter is attached to the GND and an output pin of the same group within the gate as the input(s). i.e. (1A input and 1B input requires the 1Y output). The inputs will be wired to either the GND or Vcc pins based on what the table calls for.Truth tables for each gate:Results:Input (A) NOT NOT (H/L)Low 4.91 V HighHigh 79.5 mV LowInput (A) Input (B) AND2 AND2(H/L) OR2 OR2(H/L)Low Low 0.826 V Low 334.2 mV LowLow High 0.847 V Low 4.98 V HighHigh Low 0.832 V Low 4.98 V HighHigh High 4.99 V High 4.97 V HighInput (A) Input (B) NAND2NAND2(H/L) NOR2NOR2(H/L) XOR2 XOR2(H/L)Low Low 4.92 V High 4.8 V High 365.9 mV LowLow High 4.93 V High 24.7 mV Low 4.97 V HighHigh Low 4.93 V High 23.2 mV Low 4.97 V HighHigh High 39.7 mV Low 23.4 mV Low 389.2 mV LowConclusion:I have verified the logic that had been represented by the truth table for each type of logicgate. The lows show in my data represent the zeros in the truth table, while the Highs represent the ones. From this experiment, I have gained a better understanding as to how logic gates are different and how they
