Using the A/D converter makes it possible to process __________
information with the BASIC Stamp, a digital ( __________ ) device. The
converter used in this experiment is the ADC0831 integrated circuit, an 8-
bit, __________ A/D converter.
For a given analog __________ , the A/D converter outputs an __________
binary number. The BASIC Stamp can be used to control and collect data
from the A/D converter. Various programming techniques can be used to
read, remember, and display this data.
The digital representation of the converted analog signal is very good, but
not perfect due to inherent __________ limitations of the A/D converter.
A second source of error for the Stamp DC DVM can result from the fact
that the power supply on the Board of Education does not necessarily
supply exactly 5 volts.
