By adding another NE5230 in an inverting summer
configuration at the output of the halfwave rectifier, a
fullwave can be realized. The values for the input and
feedback resistors must be chosen so that each peak will
have equal amplitudes. A table for calculating values is
included in Figure 12. The summing network combines the
input signal at the halfwave and adds it to double the
halfwave’s output, resulting in the fullwave. The output
waveform can be referenced to the supply or ground,
depending on the halfwave configuration. Again, no
diodes are needed to achieve the rectification.
This circuit could be used in conjunction with the remote
transducer to convert a received AC output signal into a DC
level at the fullwave output for meters or chart recorders
that need DC levels.
