Claim 1

APPARATUS FOR GENERATING A COMPLEX WAVEFORM HAVING A PLURALITY OF FREQUENCY COMPONENTS UNIFORMLY DISTRIBUTED OVER A DESIRED BANDWIDTH COMPRISING, A SOURCE OF PERIODICALLY VARYING ELECTRICAL SIGNALS, A PLURALITY OF DIVIDER MEANS EACH HAVING AN INPUT AND AN OUTPUT AND OPERATIVE TO PRODUCE A SIGNAL AT THE OUTPUT AT A FREQUENCY OF ONE-THIRD THE FREQUENCY AT THE INPUT, THE DIVIDER MEANS BEING CONNECTED IN CASCADE WITH THE INPUT OF THE FIRST OF THE PLURALITY OF DIVIDER MEANS BEING CONNECTED TO THE SOURCE, A PLURALITY OF MODULATOR MEANS EACH HAVING FIRST AND SECOND INPUTS AND AN OUTPUT AND OPERATIVE TO PRODUCE A SIGNAL AT THE OUTPUT COMPRISING THE SUM AND DIFFERENCE FREQUENCY COMPONENTS OF THE SIGNALS APPLIED TO THE INPUTS, EACH OF THE MODULATOR MEANS FURTHER INCLUDING MEANS TO ADD THE SIGNAL APPEARING AT THE FIRST INPUT THEREOF TO THE SIGNAL AT THE OUTPUT THEREOF, THE PLURALITY OF MODULATOR MEANS BEING CONNECTED IN CASCADE SUCH THAT THE OUTPUT OF EACH MODULATOR MEANS IS CONNECTED TO THE FIRST INPUT OF THE FOLLOWING MODULATOR MEANS, MEANS CONNECTING THE SOURCE TO THE FIRST INPUT OF THE FIRST OF THE CASCADED MODULATOR MEANS, AND MEANS CONNECTING THE OUTPUTS OF THE DIVIDER MEANS TO THE SECOND INPUTS OF THE MODULATOR MEANS IN SUCH ORDER THAT THE LOWEST OUTPUT FREQUENCY OF SAID DIVIDER MEANS IS CONNECTED TO THE SECOND INPUT OF THE FIRST OF THE MODULATOR MEANS AND SUCCESSIVELY HIGHER FREQUENCY OUTPUTS OF THE DIVIDER MEANS ARE CONNECTED IN SEQUENCE TO THE FOLLOWING MODULATOR MEANS.
