Activity 2.4.1 Conclusion

Using the Digital Logic Board (DLB), build and test your Date of Birth design. Verify that the circuit is working as designed. If it is not, do not change your design. You know that your design is good because you simulated it. If your circuit isn’t working correctly, you must have built something incorrectly. Review your circuit implementation to identify your mistakes, make the necessary corrections, and retest. Be sure to document all changes in your engineering notebook.

Activity 1.2.2 Analog and Digital Signals

Assigned: Monday, November 9, 2015
Due: Wednesday, November 11, 2015

In this activity you will examine several analog and digital signals to determine their amplitude, period, and frequency. Additionally, you will gain experience using the oscilloscope within the Circuit Design Software (CDS).

1. For each of the two analog signals shown below, determine their amplitude (peak), amplitude (peak-peak), period (T), and frequency (f). Be sure to put your answer in proper engineering notation and use the correct units.

1a. Analog - Amplitude (Peak) *

1a. Analog - Amplitude (Peak to Peak) *

1a. Analog - Period *

1a. Analog - Frequency *

1b. Analog - Amplitude (Peak) *

1b. Analog - Amplitude (Peak to Peak) *

1b. Analog - Period *

1b. Analog - Frequency *

Why isn’t the above signal considered a digital signal? *

2. For each of the two digital signals shown below, determine the amplitude, period (T), frequency (f), time high (tH), time low (tL), and duty cycle (DC). Be sure to put your answer in proper engineering notation and use the correct units.

2a. Amplitude *

2a. Period *

2a. Frequency *

2a. Time High *

2a. Time Low *

2a. Duty Cycle *

2b. AmplitudeUntitled *

2b. Period *

2b. Frequency *

2b. Time High *

2b. Time Low *

2b. Duty Cycle *

3. Using the Circuit Design Software (CDS), enter the test circuit shown below. This circuit consists of a CLOCK_VOLTAGE, a DC_POWER (battery) and two 5v LAMPS. This circuit doesn’t really do much of anything useful other than make the two lamps flash, but we will be using it to gain experience using the oscilloscope to measure signals.
You will not turn question 3 in with this assignment. You will submit it in a later activity.

a) Open the CLOCK_VOLTAGE component by double clicking on it and set the frequency, duty cycle, and voltage to 20 Hz, 10%, and 5 volts.
b) Likewise, open the DC_POWER and set the voltage to 5 volts.
c) Finally, connect the OSCILLOSCOPE to the positive side of the CLOCK_VOLTAGE component.
d) Start the simulation. Are the lamps flashing? Does the flashing rate make sense for the frequency and duty cycle of the CLOCK_VOLTAGE? If not, review your setup and make any necessary corrections.
e) Now that the circuit is working, use the oscilloscope to measure the signal being generated by the CLOCK_VOLTAGE. Use the markers to measure the period, time high, and time low. Use this data to calculate the frequency and duty cycle of the signal.
f) Do the measured (and calculated) values match those set up in the CLOCK_VOLTAGE device? If not, review your measurements and make any necessary corrections.
