Dobrý večer, pane Federmanne. Říkal jsem si, že toto Vás bude určitě velmi zajímat. Jde o měření inovovaného Audio Bufferu (http://web.telecom.cz/macura/buffer_en.html), zisk obvodu je 20dB, na 100kHz Vaší oblíbenou X-Y metodou. Měřítka vyčtete ze záznamu.

Dále bych si dovolil poukázat na ekvivalenci X-Y metody a Y-T zobrazení. Bude to na 1MHz, jelikož na 100kHz není nic vidět.

Pěkné a zajímavé řešení. Ten první OZ má ještě možnost vykompenzování nuly, pak by to bylo ještě pěknější.

To je nedbalým nastavením osciloskopu, DC složka na výstupu je kolem 1mV (OZ má offset cca 100mikrovoltů).
