Homework 1
1.
Name two advantages of digital data as compared to analog data.
a.
Two advantages of digital data as compared to analog data is that data transfer is
more effective and less noise alteration.
2.
Which quantities are more affected by noise: analog or digital?
a.
Analog is more affected by noise.
3.
List any three common products that measure analog quantities
a.
Three common products that measure analog quantities are Thermometer,
Voltmeter, and Pressure Gauge.
4.
Can a digital system exist over a complete interval of time? Why or why not?
a.
A digital system cant exist over a complete interval of time. This is because digital
systems complete one cycle in one time frame.
5.
Define the sequence of bits (1s and 0s) represented by each of the following sequence of
levels:
a.
HIGH, HIGH, LOW, LOW, LOW, LOW, HIGH, HIGH
i.
11000011
b.
HIGH, LOW, HIGH, LOW, HIGH, LOW, HIGH, LOW
i.
10101010
6.
List the sequence of levels (HIGH and LOW) that represent each of the following bit
sequences:
a.
10000101
i.
HIGH, LOW, LOW, LOW, LOW, HIGH, LOW, HIGH
b.
11110011
i.
HIGH, HIGH, HIGH, HIGH, LOW, LOW, HIGH, HIGH
7.
For the pulse shown in Figure 1–60, graphically determine the following:
a.
Rise time: 0.55 μs →
550ns
b.
Fall time:
0.6 μs →
600ns
c.
Pulse width:
2.7μs
d.
Amplitude:
10V
8.
Can the digital waveform in Figure 1–61 be called a pulse train?
a.
Yes, the digital waveform is a pulse train because the pulse per time interval is
repeating.
9.
What is the frequency of the waveform in Figure 1–61?
a.
f

10. Is the pulse waveform in Figure 1–61 periodic or nonperiodic?
a.
The pulse waveform is periodic because it repeats every 4ms.

Evaluate the use of analogue and digital electronic devices, in complex systems like a scientific calculator and an amplifier.
For the calculator
look at the input components such as chips (IC) on a circuit board, switches what do they do. The processor (microprocessor) chip (IC), central processing unit (CPU), what does it do. The output, display screen LCD, what does it do. The power source, batteries, lithium, alkaline.
Where would you expect AND, OR, NOT, EXOR gates to be used. What are FULL ADDER/HALF ADDER circuits show the circuits. How is multiplication done.
For the amplifier
Look at the input, a small voltage/current is applied, uses the power supply to help to increase the input signal, via a transistor/op-amp integrated circuit (IC).
Uses, to drive headphones, speakers. Types of amplifiers, Audio frequency, Radio Frequency, video amplifiers etc. Classes of amplifiers such as class A, B, C and AB.

Design a circuit that controls the passage of a signal "A" with the specifications:
1. Output X will equal A when control B and C are the same
2. X will remain HIGH when B and C are different.
Hint: Set "A" input as a CLK pin.
