D/A and A/D converters

____ interface between analog signals and the circuitry of digital devices

Specific applications of D/A and A/D converters include

• Pulse modulated communications

• Radar systems

• Audio systems

• Video systems

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 ___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 ___ the resistance of the rung before it

The MSD input is the ___ resistor(R1) in the network where the MSD of the binary number is applied and has the most current

Answer explanation

The smallest resistor value is R1

____ 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 _____ section gates the analog input to the Hold Section when a positive sample pulse is applied
