 		 #186629 - Precision rectifier is suitable for any waveform
Responding to: ???'s previous message
Yagnesh Mehta said:

is there any other limitation? i know precision rectifier is not suitable for chopped wave but i do not have any proof and solid reasons(proved on paper)....

Precision rectifier is suitable for any waveform, the limitations are as I stated earlier, so you won't find that proof or solid reasons.

      Okay            01/01/70 00:00      
         Are many threads available            01/01/70 00:00      
      when you save a char ...            01/01/70 00:00      
      Why don't you specify your problem COMPLETELY?            01/01/70 00:00      
         Already specify it            01/01/70 00:00      
            there are some details?            01/01/70 00:00
