Annotations languages:

The peculiarities of FPGA implementation of multichannel bioimpedance analyser are discussed. The necessity of freeform signal obtaining for testing of existing project of the bioimpedance analyser is shown. The analytical overview of the possible ways of hardware implementation of signal shapers with the defined characteristics is given. Task solutions of the development of 80 MHz freeform signal generator with constraints of FPGA resources are given. The block diagram of the memory synchronization unit of the FPGA-based signal shaper is offered.
