By adding another NE5230 in an inverting summer
configuration at the output of the half
wave rectifier, a
full
wave 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 half
wave and adds it to double the
half
wave’s output, resulting in the full
wave. The output
waveform can be referenced to the supply or ground,
depending on the half
wave 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 full
wave output for meters or chart recorders
that need DC levels.
