circuit(PID).
3)
4)input and output signals are on the circuits.5)summer:the output is the sum of the input
voltages.Integrator:produces a ramp of output voltage,which is a linearly increasing or
decreasing voltage.Differentiator:produces an output voltage proportional to the instantaneous
rate of change of the input voltage.PID:They amplify the beginning and the end of the pulse
signal.6)Summer:Uout=-(U1R/R1+U2R/R2+U3R/R3).Integrator:Uout=-1/T
int(Uindt);Iin=Uin/R;Uout=-Iint/C = -Uint/T;Uout= -Uin/(4fT).Differentiator:Uout= -T
dUin/dt.PID:K=R2/R1;T1=R1C1;T2=R2C2
7)Substracter:The output voltage,which is proportional to the difference of the input voltages
when R1=R2 and R=R3.
Logarithmic:It is the inverting amplifier with a feedback diode rather than feedback
resistor.Once the diode and the resistor positions replace on other, the exponential amplifier
appears:
