Activity 1.2.5
Introduction
Even though this is a course in digital electronics, it is important to understand that the world around us is analog. Virtually everything that can be designed with digital electronics is used to either control or monitor something in the world around us, and this world is analog. Thus, to be an effective designer of digital electronics, it is important for you to understand the characteristics of both analog and digital signals.
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).

Conclusion
1. List the characteristic that makes a digital signal different from an analog signal.
Digital signals are discrete, have a finite range of values, and their signals can't be negative.
2. In the diagram shown below, label the parts of the analog signal.
A.Amplitude(peak-to-peak)
B.Amplitude(peak)
C.Period
3. In the diagram shown below, label the parts of the digital signal.
A.Amplitude
B.Time high
C.Period
D.Time low
E.Rising Edge
F.Falling Edge
4. What are the two standard voltage levels that are acceptable for a digital signal?
The two standard voltage levels acceptable for a digital signal are 0 and 5.
