Hi guys, I am trying to implement an Automatic Street lights system using LTSpice. LDR output is given to me as a text file, which I am loading as a PWL file
Because the data will have spikes, I tried to implement a basic LPF. But when the output is taken from op amp, I am getting very strange data..certainly not what I expected. When I am googling about LPF in LTspice, I could find data only about frequency response...
Pls help guys..

 

hi NN,
Welcome to AAC.
Please post your PWL file.

Why are you using LTspice for such a simple circuit?

Post your schematic and describe the difficulties you're experiencing.
