A set of ___________ voltage values sent to the inputs of a resistive ladder
network results in a ___________ voltage level at the output. This method
is an inexpensive alternative to integrated circuits. Its advantages are
flexibility in resolution and low cost. Its main disadvantage is accuracy.
The
___________ within a nibble, byte or word. This can be used to select bits
from a binary number in memory and set ___________ values equal to
those bits.
PBASIC can be used to address BASIC Stamp I/O pins a bit at a
___________ at a time, or alternatives exist for ___________ nibble, byte
or word size groups of I/O pins. This allows the ___________ and output
values of the I/O pins to be addressed as groups of bits instead of as a
single bit.
A voltage ___________ can be run on a D/A converter. This allows one to
view the D/A converter's outputs for all possible binary inputs. The BASIC
Stamp can be programmed to ___________ this process and display the
data in a table format.
The voltage follower can be used as a buffer, which can supply extra
___________ to the input of a circuit connected to the D/A converter's
output.
