Chapter 6 - Encoding, Decoding, and Seven-Segment Displays
- Refer to Fig. 6-1. Data would be transferred
from the calculator circuitry to the group of 7-segment
displays using the ___ (BCD, EBCDIC) code.
- Refer to Fig. 6-1. If the data transferred
from the calculator circuitry is 0000 0000 0110 1001 0111
1000 0001 0101BCD, what will the decimal indication on
the calculator display?
- Refer to Fig. 6-2. Data would be transferred
from the computer circuitry to the output display (perhaps
on another computer) using the ___ (ASCII, BCD) code.
- Refer to Fig. 6-2. If the stream of
data transferred from the computer circuitry is 0000010
0100011 0100000 1000100 11001001 1100111 1101001 1110100
1100001 1101100 0000011ASCII, what will the alphanumeric
display read? The spaces between the 7-bit groups are
for your use and may not appear in a real data stream.
- ASCII is a 7-bit code used in computer
technology. List several 8-bit codes also used to represent
alphanumeric information. (use www.pcwebopedia.com)
- Refer to Fig. 6-3. Label the parts
of the diagram (A, B, and C) for 7-segment LED display
circuit.
- Refer to Fig. 6-3. What will the decimal
readouts be for the following inputs (assume a common-anode
type 7-segment display):
- HLLHHHH (order= a to g)
- LLLLLLL (order= a to g)
- LLLLHHL (order= a to g)
- LLLHHHH (order= a to g)
- HHLLLLL (order= a to g)
- HLHHLHH (order= a to g)
- LLLLLLH (order= a to g)
- Refer to Fig. 6-4 (prepared with Electronics
Workbench®, Version 5). Use circuit simulation software
to draw this BCD-to-7-segment LED display decoder/driver
circuit. Add switches to inputs A-D to test the circuit.
Show the simulation to your instructor.
- Refer to Fig. 6-5. What technology
is used to manufacture this display?
- Refer to Fig. 6-5. Identify the parts
of this LCD display (A-F).
- Refer to Fig. 6-6. What technology
is used to manufacture this display?
- Refer to Fig. 6-6. Identify the parts
of this VF display (A-D).
