astabile a operazionali

astabile a operazionali riferendoci alle formule offerte nel link progettare un multivibratore astabile oscillante a 1 khz alimentarlo con +-10V usando il tl 082

adattarlo per ottenere una variazione del duty cycle almeno dal 20% all'80%

SCHMITT TRIGGER lab test n°2

• Build or simulate a Schmitt trigger using an Op Amp (LM741 if possible).
• Measure the characteristics of the Schmitt trigger you made.
• Use a DC power supply of +-10V and set the generator on a 3V amplitude.
• Compare the signals at the point 2 and 1 on the schematics with an oscilloscope.
• Measure the thresholds of the Schmitt trigger  and compare them with the calculated values ( literature is linked below).
• Replace R1 with a 12Kohm resistor and check and explain what happens.
• Change the amplitude of the input to 1V and check what happens.
• Draw the input-output graph for this device.
