Problem converting from Eb/N0 to SNR

I'm doubtful about which of these is correct:$frac{E_b}{N_0}=frac{SNR}{k}frac{T_{symbol}}{2T_{sampling}}=frac{SNR}{k}frac{L}{2}$$frac{E_b}{N_0}=frac{SNR}{k}frac{T_{symbol}}{T_{sampling}}=frac{SNR}{k}L$$L$ is the interpolation factor and $k=log_2(M)$ (number of bits per symbol). There's just a difference of a ...
