Testing of Middle-resolution Digitisers at Input Signal Frequency of 1 MHz

A system for the testing of digitisers in the frequency range of 1 MHz was developed at the Dept. of Measurement, CTU FEE a few years ago. Two alternates of the system were manufactured - a precision design using special high-quality LC filters with a near-linear transfer characteristic and a low-cost design employing common LC filters using coils with ferromagnetic cores. Both alternates were used for testing several types of middle-resolution digitisers
