We had to use the logic probe in order to et the output which we would assign as Is as high and So as IoW 8. When we used the probe on different pins of the inverter 7404 (see Picture 1, Appendix) we noticed that ground connection was IoW no matter what as well as input was corresponding to the IoW when switch was off and high when switch was on. The obtained output was inverted when the switch was on it was IoW and high when the switch was off. Pin 14 stayed at a constant voltage not depending on the position of the switch. After replacing the wire connecting pin 14 to the +V we get the IoW probe 9. After we touched the probe on pin and pin we noticed that the logic levels were complemented: a. The probe on pin indicated IoW and after flipping the switch it indicated high b. The probe on pin indicated high and after flipping the switch it indicated IoW 10. After connecting pin to the frequency generator TTL output and setting the frequency to 1 Hzs we observed a low blinking indicator (around 1 blink per sec). 11. When we increased frequency of the signal to 100 kHz we observed a pulsating high indicator which we could be only seen on the logic probe which gave us reason to think that such a high frequency generated alternating output. 12. The investigation of the 7486 exclusive OR (XEROX) by connecting 2 logic switches and a logic indicator to the two inputs and the output of the XEROX gates gave us following results the output was IoW only when both of the switches are IoW and one of the switches was on IoW and another on high ; and the output was high only when both switches were on high. Which was identical to the theoretical data (see Picture 2 Appendix). 13. The behavior of the following chips is provided below in the Table 1 (please see Appendix) please notice that in the table e refer to the AND Functionality when both of the switches are located on the same position and OR Functionality refers to when one of the switches is on and another is off. Results and Conclusion The ICC Chips which behavior we observed in our experiments were connected to the CADET Station, the experimentally obtained data proved that logic gates functioned exactly as intended. We connected the inputs to logic switches, and the outputs to logic indicators as needed we used the logic probe in order to see the obtained the outputs for the given logic gates (see Table 1, Appendix) and compared hem to theoretical values in both cases outputs were the same. It was vital to perform the connections well with the supervision of the instructor in order to obtain the correct results in order to perform this successful experiment from design to implementation and verification.
