    Hi ,

    It is a little difficult to understand these waveforms as it is not clear if and how they align in time.

    I have some questions about the INHIBIT waveform. Do you know what is happening when the waveform disappears just after the 0 x-division (center)? Before the signal disappears, with the high level of the INH signal at 400mV, the part should be disabled. Is this the case, or is this where the output appears to be toggling in the 3rd waveform?

    Again, it is unclear if/where these 3 signal waveforms align in time (x-axis).
