Orthogonalization of the signals is achieved by release of Mk leading edges of signals fk and the normalization of their duration. Code-frequency converter. For frequency synthesizers based on pll core elements that a voltage-controlled oscillator. The above method of frequency synthesis can be applied to construction of generator-driven code. It only needs to assess (estimate – in the case of the simultaneous formation of several frequencies) required the current members of a number of Mk, which corresponds to k bits manager (s) code (s): if k bits in the control code – used for the synthesis signal fk, otherwise – no. vhdl source code of two inverter-frequency code.
