Q

Analog Signal

A
  1. Continuous value reporting
  2. Infinite range of values
  3. More precise than Digital, but more difficult to work with
    Ex: radio waves
17

  2. Amps (peak-peak)
  3. Period (T)
  4. Frequency (f)
18
Q

Analog Waves

A
  1. SIne Wave
  2. Square Wave (only when it changes direction + to -)
  3. Random - Periodic
19
Q

Digital Signal

A
  1. Commonly referred to as square wave/clock signals
  2. Minimum - 0V
  3. Maximum - 5V
20
Q

4. Time Low (tL)
5. Falling Edge
6. Rising Edge
7. Frequency (f)
8. Duty Cycle (%)

21
Q

Digital Wave Type

A

Square Wave

22
Q

Period (T)

A

the time (sec) it takes for ONE CYCLE to repeat itself

23
Q

Frequency (f)

A

how many cycles in 1 second (base unit)
f = 1/T = ____Hz

24
Q

Duty Cycle

A

DC = (tH/T) x 100 = _____%
* the answer has to be less than 100 for it to make sence since it is a % answer

25
Q

Can you process digital signals?

A

No, only analog

26
Q

Real life examples of Digital & Analog

A

Digital - iPhone, Netflix
Analog - landline, a TV w/ antenna

27
Q

What is ratio’s unit?

A

Ratio does not have a unit, just labeled %
