    Hello,

    I want to know if it is possible to make an equivalent circuit of the simple RLC circuit attached using Operational Amplifiers.

    I want to represent the voltage signal shown, but I don't know how.

    It depends on what you want to do!

    Op-amps can be used to substitute for inductors but using more capacitors. I have never done it but have seen it described in "Electronic Filter Design" by Arthur B. Williams, there is a later book by Arthur B Williams and Fed J. Taylor also.

    The circuit you show would need its response calculated and could be simulated with a single op-amp band pass filter.

    Thank you for the information, I think I will look for more information about the band pass filter you mention.
