Abstract (en)

[origin: DE19618098C1] A circuit arrangement for generating random bit sequences has a first oscillator (OSZ1) and a second oscillator (VCO1) whose outputs are connected to the inputs of a phase detector (PD) that generates the random bit sequence. The second oscillator (VCO1) is frequency modulated.
