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.
