Abstract: A system and method of recording and reproducing wide band channel information by means of several narrow band channels involves sampling of wide band channel information, providing respective samples to corresponding narrow band channels wherein recording and reproduction take place, reproducing the narrow band signals, amplifying and shaping the reproduced narrow band signals, and then combining and amplifying the resulting narrow band signals to reproduce the original wide band signal. A preferred embodiment of the present invention involves dot interlacing the received wide band information signals in accordance with a derived sync signal to derive sample pulse outputs. Various embodiments are provided for shaping the reproduced narrow band channel signals in accordance with "phase modulation", "amplitude modulation", and "frequency modulation" modes of operation.
