====== Signal Invert ======
\\
{{:resources:tools-software:sigmastudiov2:modules:arithmeticandlogic:invert.png}}
===== Description =====
The SignalInvert block inverts the polarity of the incoming signal.Signal invert entails a 180-degree phase shift, making the positive components of waveform to negative and negative components of waveform to positive.
