# 4-bit Quantum Fourier Transform Circuit with specific / custom Gates [closed]

I am studying the Quantum Fourier Transform and completing some exercises.

I want to write the circuit for the 4-bit Quantum Fourier Transform in terms of specific gates: H, controlled-V, and C-NOT, where H is the Hadamard gate and $$V=\mathrm{diag}(1,e^{\pi i/8})$$.

So basically I need to rewrite the H and $$R_k$$ gates in terms of these. Is there s a relation between phase-changing gates that I am missing?
