A proof that the functional equation technique of dynamic programming can be used advantageously in analyzing weighted pulse-code modulation (WPCM) communication systems. WPCM differs from normal PCM in that the amplitude of the transmitted pulses representing the binary digits in a pulse-code group is made to depend on the size of the group and on the power of two represented by the individual pulses.
