| - Find in the {{https://cdn-shop.adafruit.com/datasheets/Users+Guide+DS1000E.pdf|Instruction of the oscilloscope}} the values of the input impedance, which are needed in the circuit for the input resistance $R_\rm E$ and the input capacitance $C_\rm E$. \\ Replicate the circuit in using the information from TINA TI above (**Circuit 1**). Take into account the input impedance of the oscilloscope, as shown in the sketch. \\ Simulate circuit 1 with the specified signal. Briefly describe the expected and measured signal waveforms. | - Find in the {{https://cdn-shop.adafruit.com/datasheets/Users+Guide+DS1000E.pdf|Instruction of the oscilloscope}} the values of the input impedance, which are needed in the circuit for the input resistance $R_\rm E$ and the input capacitance $C_\rm E$. \\ Replicate the circuit in using the information from TINA TI above (**Circuit 1**).

| - Since something seems to be funny, you want to debug the circuit, that is, determine the error. To do this, you could use the [[elektronik_labor:tipps_fuer_die_fehlersuche#allgemein|generic approach to debugging (in German)]]. Or you break down the unclear system to a minimum. Specifically, you build a modified circuit (**Circuit 2**): | - Since something seems to be funny, you want to debug the circuit, that is, determine the error.
