Abstract
This article discusses the issue of studying the parameters of the bounce of electrical contacts of switches in digital systems. Digital circuits of bounce analyzer are described. The results of experimental studies of the behavior of electrical contacts of various buttons and switches are presented. It is shown that various electric switches have random and unique characteristics, which can be used to solve the problems of random numbers generating, identifying of digital devices and user’s authentication. Prototyping of the proposed circuits was carried out on Digilent ZYBO Z7-10 debug boards, digital circuits were designed in VHDL for the Xilinx Zynq-7000 FPGA chip.
