DEVELOPMENT OF DIGITAL FUNCTIONAL CONVERTERS OF THE MODULATING VOLTAGE ON THE BASIS INTERPOLATING METHODS FOR USE IN QUADRATURE SHAPERS OF THE RADIO NOISE WITH ANGULAR MODULATION
In paper is lead comparison of analytical, tabulared and tabulared-algorithmic methods of implementation sinus and cosinus functional converters (FC) of a modulating voltage from the point of view of accuracy of transformation provided with them and computing expenses. The estimation of making mistakes of piece-linear interpolation for tabulared-algorithmic method FC is produced. The leading-out is made, that tabulared way FC with a preliminary low-frequency filtering of an arrival signal is optimum for technical implementation with use of digital computers and maintenance of required accuracy of formation radio noise with angular modulation
