Abstract

The use of quasi-harmonic signals is one of the efficient methods for increasing the performance attributes of switching oscillators. The power of the higher harmonics of a 4-step quasi-harmonic (QH) signal amounts to approximately 1%, while the number of the higher harmonic closest to the first harmonic is equal to 15 (see [1]). An optimal method of generating a QH signal is the formation of the signal on the basis of Walsh functions, the output voltage being determined by the expression (see [1])…
