Figure 11. Practical realization of the EKG amplifier
The electronic circuit was assembled on two dubly copper placated test plates which were
placed on a chassis made up of a hard plastic plate (Figure11). The preamplifier was armoured with
an iron plate to reduce the influence of the electric network. The entire assembly was introduced in
a plastic box specially designed for electronit fittings. The linking cables of the three electrodes are
also armoured and connect to the electronic module via RCA sockets.
