I want to combine 2 digital filters (2.5 KHz bandwidth each) in some way so that combined response of both these filter can extract a 5 KHz bandwidth signal from a given input spectrum.
If it is possible kindly guide me how can I do that.

Because you have relative big distance between bands, better than a BPF is to add a diplexer (not duplexer) where the antenna combines.
A diplexer is a combined LPF and a HPF. They have wider rejection bandwidth and also have lower in-band insertion loss than a BPF (or a duplexer which is a combination of BP filters).

We can decompose signal (x(t)) by transforming to frequency domain, as u know:
that, A,B,C,D are amplitude of single-frequency signal that combined and create the x(t).
