one-step Code

An improved one-step Code (reflected code) i.e. that only one bit changes from one entry to the next. This code gets two bits out of one stripe of code, and therefore needs only half of conventional necessary code stripes on the encoder plate. It can replace the well known Gray-Code, first described by Frank Gray in 1953, giving smaller and cheaper encoding devices.

Graph paper
single logarithmic graph paper (landscape, abszissa 4 dekades)
double logarithmic graph paper (landscape, abszissa 4 decades, ordinate 3 decades)
checked pattern paper for arithmetics is cheaper in paper stores.
music paper with 12 lines per page, if you need right now.

All with 18 cm x 28 cm print area (about 7 inch x 11 inch).
