Square wave at 20 Hz falling roof is because your oscilloscope is on AC input , change it to DC input you will see the real signal , AC input on scope at low frequency will make time constant with scope capacitor 👋👋👋👋👋👋
Yes, you are correct with the "falling roof" effect where the signal appears to droop or decay over time. This is due to the capacitor's time constant interacting with the 20 Hz low-frequency signal. Thanks.
Excellent video. This channel has a lot of dedication to provide precise information about high quality amps. Thanks for all you do.
Thanks.
Excellent
Excelente video. Gracias por compartir tus conocimientos.
