Question

design a basic band pass filter comprising of a series combination

Answer 1

See the diagram.

Here is a design for a Band pass filter, Constant K based T-Section .. 

    K1 = √(L₂ / C₁)  for HPF part.
    K2 = √(L₁ / C₂)  for the LPF  part.
    L₁ C₁ = L₂ C₂ = 1/ω₀²
    
    ω₀ = √(ω₁ ω₂)
         ω₁,  ω₂ are the cut off frequencies (Lower and Higher) for the band pass filter.    ω₂ - ω₁ = band width of the filter.

  From desired and given K1, K2 and ω₁ , ω₂  we can find the electrical circuit elements.
