An apparatus for detection of digital signals comprises a reset integrator, a sampling switch, a decision-making circuit, a control circuit, two-way symmetrical limiter, threshold levels of which can be changed. Input of the apparatus is connected with input of the symmetrical two-way limiter. Outputs of the two-way symmetrical limiter are connected with the reset integrator input. Reset integrator output is connected with the sampling switch; output of the said switch is connected with input of the decision-making circuit, output of which being output of the apparatus. Pulse sequences from the control circuit are supplied to control inputs of the reset integrator and the sampling switch. |
