CONFIGURATION FOR THE DIGITAL-ANALOG CONVERSION OF A HIGH-FREQUENCY DIGITAL INPUT SIGNAL INTO A CARRIER-FREQUENCY ANALOG OUTPUT SIGNAL

摘要

The arrangement has a delay device with at least one first delay element. The input signal is fed to inputs of the first delay element and of a first digital to analog converter or DAC. Delay element outputs are input to associated DACs. All DAC outputs are combined so their output signals form the analog signal. Each DAC has a specific coefficient and each delay element a specific delay time to form a filter characteristic. The arrangement has a delay device (VZ) with at least one first delay element (VG1,..) and further delay elements in series. The input signal (DE) is fed to inputs of the first delay element and of a first digital to analog converter (WD). The first and possibly further delay element outputs are input to associated digital to analog converters. All digital to analog converter outputs are combined so their output signals form the analog signal. Each digital to analog converter has a specific coefficient (k0,..) and each delay element a specific delay time (t1,..) to form a filter characteristic.
