Abstract
A digital-analog converter for mobile radiotelephone base stations includes a D flip-flop and a modulator. The D flip-flop is clocked by a clock signal and a digital input signal is fed to an input of the D flip-flop to produce an output signal. The modulator multiplies the output signal produced from the D flip-flop with the clock signal and outputs an analog output signal indicative thereof.

A digital-analog converter for mobile radiotelephone base stations, comprising:
- a D flip-flop clocked by a clock signal, wherein a digital input signal is fed to an input of the D flip-flop to produce an output signal;
- and
- a modulator to distort the clock signal and produce a distorted clock signal having passages through zero that are delayed, the modulator multiplying the output signal from the D flip-flop with the distorted clock signal and outputting an analog output signal indicative thereof.
