ECE 392 Lab 7: Digital Circuits Quiz

Abigail, Nora, and Anika are having a debate. Abigail says that the main difference between logic gates and flip-flops is that flip-flops have memory, but logic gates do not. Nora thinks it's because flip-flops depend on clock pulses, but logic gates do not. Anika believes that logic gates depend on clock pulses, but flip-flops do not. And there's a fourth opinion that logic gates have memory, but flip-flops do not. Who do you think is correct?

• Abigail: Flip-flops have memory, logic gates do not

• Nora: Flip-flops depend on clock pulses, logic gates do not

• Anika: Logic gates depend on clock pulses, flip-flops do not

• Fourth opinion: Logic gates have memory, flip-flops do not

Charlotte, Abigail, and James are working on a digital circuit project. They are debating about the recommended voltage range for input states in digital circuits. Can you help them out?

• 0-5 V

• 0-3.3 V

• 0-12 V

• 0-1.8 V

Isla, Emma, and Noah are working on a digital systems project. They are considering using simple diode gates. But Noah remembers there's a main disadvantage to using them. Can you recall what it is?

• They can only perform basic logic functions

• They are not reliable

• They draw too much power

• They have undefined states

Aria, Emma, and Abigail are working on a digital circuit project. They come across a component called a switch debouncer. Can you help them understand what the purpose of a switch debouncer in a digital circuit is?

• To generate multiple pulses for each switch closure

• To eliminate the switch bounce effect

• To synchronize all pulses with the clock signal

• To increase the frequency of the input signal

Aria, Ava, and Lily are working on a digital systems project. They are debating about the main advantage of using CMOS circuits in their design. Can you help them out?

• CMOS circuits have better tolerance for undefined input states

• CMOS circuits have faster switching speed

• CMOS circuits have higher output voltage levels

• CMOS circuits have lower power consumption

Hannah, Olivia, and Henry are working on a digital circuits project. They are having a debate about the function of an exclusive OR gate (XOR). Can you help them settle the debate?

• It performs logical OR operation

• It performs addition of binary numbers

• It performs logical AND operation

• It performs subtraction of binary numbers

Aria, Aiden, and Charlotte are working on a project about flip-flops in their computer science class. They are having a debate about the purpose of using a clock signal in flip-flops. Can you help them settle the debate?

• Aria thinks it's to eliminate the switch bounce effect.

• Aiden believes it's to control the output voltage levels.

• Charlotte argues that it's to synchronize the state changes.

• Or is it to increase the frequency of the input signal as suggested by their teacher?

Imagine Olivia, Benjamin, and Noah are working on a digital circuit project. They are debating about the main reason for tying unused inputs to the power source or ground in digital circuits. Can you help them settle this?

• Olivia thinks it's to improve the reliability of the circuits.

• Benjamin believes it's to increase the voltage levels.

• Noah suggests it's to decrease the power consumption.

• Or is it to avoid undefined input states, as their teacher suggested?

Imagine Aria, William, and Maya are in a laboratory experiment. They come across a resistance substitution box. Can you guess what they would use it for?

• To control the input voltage levels

• To vary the voltage at the gate inputs

• To measure the resistance of the digital circuits

• To eliminate the switch bounce effect
