Abstract:
1. A communication system comprising: a receiver structured to receive a substantially continuous sine wave carrier signal, the signal modulated to contain communication data; a demodulator communicating with the receiver, the demodulator structured to demodulate the communication data from the substantially continuous sine wave carrier signal; and an ultra wide band transmitter coupled to the demodulator, the transmitter including an electromagnetic pulse generating circuit, with the electromagnetic pulse generating circuit structured to transmit a plurality of electromagnetic pulses, with the pulses configured to include the communication data, wherein the electromagnetic pulse generating circuit comprises: a control unit; at least two current sources; at least two switching elements connected to the current sources, each of the switching elements structured to receive a signal from the control unit; a switch connected to the at least two switching elements, the switch structured to receive a signal from the control unit; a load connected to the switch; and a first set of resistive elements connected to the current sources, and to the switching elements, the resistive elements also connected to a second voltage level.
