Control motors using a password
Encrypt passwords using logic gates
Which password will activate the GREEN LED?
12
21
22
33
What kind of output is shown on the two 7-segment displays?
Binary representation
Entered password digits
ASCII codes
LED error code
What type of component is used to compare the entered password with the correct one?
Priority encoder
Flip-flop
Comparator
Decoder
A common cathode 7-segment display is active HIGH.
True
False
The system uses synchronous memory to store the outputs from the 7-segment decoder.
True
False
The priority encoder outputs a 2-digit BCD number from multiple button presses.
True
False
The AND gate is used to activate the RED LED.
True
False
The 7-segment decoder converts _______ bit inputs into ________ outputs to drive the display.
(a)
To store a single bit in memory, the system uses a Flip-Flop and a (a) .
What would the following line in Verilog likely represent?
assign green_led = (entered1 == 2 && entered2 == 2);
Why would we need a MUX in the memory design of this security system?
