The purpose of a D/A converter is to convert digital data (binary) into analog signal (current, voltage, or electrical charge)
True
False
In a D/A converter, the binary number is the input, the (a) voltage is the output
In a resistor network, ____ is the base resistor and all other resistor values must be referenced to it
R1
R2
R3
R4
In a Resistor network, each rung in the ladder must be (a) the resistance of the rung before it
The MSD input is the (a) resistor(R1) in the network where the MSD of the binary number is applied and has the most current
(a) A/D converters take analog input and processes it to develop a digital output
A Ramp A/D converter is divided into which sections?
Sample
Hold
Compare
Digitize
Synthesizer
The (a) section gates the analog input to the Hold Section when a positive sample pulse is applied
In a Ramp A/D converter, the more digits of resolution or bits there are, the more (a) the conversion
In a Ramp A/D converter, the digitize section develops a binary count (a) proportional to the analog input
The (a) Section stores the analog voltage to be used in the Compare Section
The (a) Section compares voltage from C1 and produces a STOP pulse when the sweep signal exceeds the analog sample
(a) law is used to determine the output voltage of the D/A converter
