The first harmonic constituent has the most investment in amplitude of sampled signal of meander type. The filter of high order is needed to select a signal. Fig.1,a - transformation of meander in sinusoid on a logic 2-Input XOR Gate and D-triggers is realized. The IC U1 is “Eliminating OR” or sum on the module 2, U2 – divizors of frequency. Input and formed signals with the proper coefficients are summarized on the IC U3. Fif.1,b - the result of summarizing. Fig.1,c – oscillogram on the output of circuit after filtration. Frequency of output signal is in 3 times lower from an input frequency.
