Approximation theory is concerned with how functions can best be approximated with simpler functions called base functions and with quantitatively characterizing the errors introduced thereby [1]. One of these base functions is Block Pulse Functions (BPFs) [2] on which some researches are based. However BPFs are very common in use, it seems their convergence is weak and some published papers have tried to improve the speed of BPFs convergence with different methods like hybrid BPFs [3–5]. In fact by referring to error bound of BPFs approximation it seems for achieving double precision, number of BPFs have to be doubled which means solving systems of equations with double unknowns and double equations [1,6].
