Device for generating quasi-analog, poor power loss transmission signals, has multiple power supplies, which are placed selectively at transmitter stage by switch, in order to provide output signal with amplitude modulation

摘要

The device has multiple power supplies (DC1-DC7), which are placed selectively at a transmitter stage by a switch (S0-S7), in order to provide the output signal with an amplitude modulation. The power supplies supply the same direct current-voltage. A bridge switch is provided with the switches (SB1-SB4) before the transmitter stage, in order to change the polarity of the current supply for the transmitter stage.
