The proposed device for transmitting discrete data with wideband modulation of signals contains a personal computer with a serial interface and a programmable interrupt controller, a programmable timing unit, a reference-frequency oscillator, and additionally, a Haar function generator, an AND logic element, two reference voltage sources, two comparators, two OR logic elements, two triggers, and a parallel interface. The INT0 input of the interrupt controller is connected to the output for an interrupt signal in the serial interface circuit. The output of the reference-frequency oscillator is connected to the timing inputs of the CT0 and CT1 in the timing unit circuit.
