Hey,
i ve got a homework and that is to design a audiopreamplifier with op-amp(s).
Input signal : U_e = 1 V, Sinus, 1Khz
Output signal: variable Amplitude with same frequency and variable amplification factor between 0-5. I ve create a circuit but i am not really sure how to deminsion it.
P.S. the graphic includes german resistance cause i am from Germany
