.
A multiplier can’t do nonintegral roots “exactly”, but it can
yield a close approximation. We can approximate
Figure 18 compares the function VOUT = VIN
0.7 to the
approximation VOUT = 0.5VIN
0.5 + 0.5V
IN.
This function can be easily built using an HA-2556 and a
potentiometer for easy adjustment as shown in Figures 19 and
20. If a fixed nonintegral power is desired, the circuit shown in
Figure 21 eliminates the need for the output buffer amp. These
circuits approximate the function VIN
M where M is the desired
nonintegral power or root.
