AND gate:
X is 1 if both a AND b are both 1 -- (ab or a⋅b)
OR gate:
X is 1 if a OR b OR both are 1 -- (a + b)
XOR gate:
X is one if exactly a OR b is 1 -- (a ⊕ b)
NAND gate:
X is 0 if both a AND b are 1 -- (a⋅b)'
,NOR gate:
𝑋 is 0 if a OR b OR both are 1 -- (a + b)'
X-NOR gate:
𝑋 is 0 if exactly one of a OR b is 1 -- (a ⊕ b)'
X-NOR and X-OR gates are a combination of which two other gates?
AND and OR gates
XOR gates can be converted to XNOR gates by doing what?
inverting one of the leads (a, b, or X)
Sampling (Analog to Digital Conversion, Step 1):
Conversion of a continuous signal to a discrete-time signal
Quantizing (Analog to Digital Conversion, Step 2):
Conversion of a discrete-time signal to discrete amplitude signal
, Encoding (Analog to Digital Conversion, Step 3):
Conversion of a discrete signal to binary word
Resolution/Quantization Step-Size:
The voltage represented by the least significant bit [(V-max - V-min)/N-states]
Sampling Rate:
The frequency at which the ADC evaluates the analog signal
Aliasing:
An effect that causes different signals to become indistinguishable when sampled
Nyquist Rule for Sampling:
a sampling rate must be at least twice as fast as the highest frequency to avoid aliasing
What are the 2 best ways to improve the accuracy of A/D conversion?
Increase resolution and increase sampling rate
What does a push button act like in a circuit?
a switch
