>Which is best for your DL241 modification?
>For combining control voltages from precision rectifiers for a compressor's stereo link:
>The Precision Diode OR Gate (method 2) is generally the most suitable. It's a classic and highly effective analog circuit for selecting the maximum of two continuous analog voltages, precisely, and without the contention issues of simply tying outputs together. It effectively creates a "precision maximum" detector.
>The comparator-based approach (method 3) is usually overkill and adds unnecessary complexity and potential artifacts for this specific application, where you need the instantaneous higher value of two continuously varying control voltages.
>So, when I mentioned "active OR gate" earlier, the precision diode OR gate is often the intended meaning in an analog circuit context where you want to overcome diode voltage drops. You are indeed still using diodes, but the op-amps work with them to create a precise "maximum" function.
