Digital technologies represent audio or video data using binary 1s and 0s, controlled through logic gates like AND, OR, and NOT. Analog technologies use waveforms to represent signals. While analog can send signals farther, digital uses less circuitry, is more compact, and provides clearer signals over long distances when combined with analog transmission. In general, digital is considered better for applications like phones and video games due to its compact nature, though analog remains useful for transmitting signals over long distances.

1. Digital Vs. Analog
Technologies

2. Outline
• What is Digital technologies?
• What is Analog technologies?
• Which is better?

3. Digital uses
• Clocks
• T.V
• Video
• Phone
• Video games

4. Digital uses
• Digital is breaking the signal into a
binary format where the audio or video
data is represented by a series of "1"s
and "0"s
• Digital technologies use 1’s and 0’s to control
circuits. 1’s and 0’s are controlled by logic gates
• Some logic gates used are;
• AND, OR, NAND, NOR, XOR, XNOR, NOT

5. 1’s and 0’s
• A 1 represents a true statement, also it
means ON
• A 0 represents a false statement, also it
means OFF

6. AND Gates
• A * B = AB
• 1 * 1 = 1 or 1 * 0 = 0

7. OR Gates
• A + B = A+B
• 1 + 1 = 1 or 1 + 0 = 1

8. NOT Gates
• A = NOT A
• 1 = 0 or 0 = 1

9. NAND Gates
• A * B = NOTAB
• 1 * 1 = 0 or 1 * 0 = 1

10. NOR Gates
• A + B = NOTA+B
• 1 + 1 = 0 or 1 + 0 = 0

15. Analog uses
• Clocks
• T.V
• Video
• Phone
• Video games

16. Analog uses
• Use Wave forms to control a device.
• Analog is the process of taking an audio
or video signal (in most cases, the
human voice) and translating it into
electronic pulses.

17. Which is better
• Analog uses more circuitry to control a
device. This takes up more room.
• Digital uses less circuitry to control a device
making it more compact.

18. Which is better
• Analog can be used to send a signal very far
distances. FM or AM radio
• Digital can use an analog signal to send
information very far distances but at a
clearer signal.
