Exam 3 Flashcards
Basic stuff will add more later
Major advantage of digital technology over analogue
Digital has error detection and correction
Duty cycle of a square wave?
50%
What’s the most common type of waveform?
Sawtooth
Most commonly used flip-flop?
JK F-F
Inverting Schmitt Trigger explain difference in symbol compared to non-inverting
Inverting - exit bar at top
Non- inverting - exit bar at bottom
Difference between Asynchronous and Synchronous counters
Asynchronous clock pulses dont arrive at the same instant
Synchronous arrive at the same instant in time - this is also a disadvantage
What is Fan in?
The number of inputs a logic gate can accept
What is Fan Out
The number of outputs a single logic gate can drive
What happens when J & K are high in a JK Flip-Flop
It is in toggle mode
Why is the JK beneficial over other types?
Output is interlocked?
What is propagation delay measured in?
50% of Vmax point
Whats the slew rate measure in terms of Vmax
10% & 90%
What type of counter uses clock pulse?
Asynchronous
Explain a digital waveform?
On or Off
Are Up counters triggered in postive or negative?
Negative
