Digital triangular wave quadrature oscillator
Milan Štork · 2017
Digital oscillators are a useful electronic system that can be used for different applications. Usually the frequency and amplitude stability is important. There are oscillators with different type of output signal e.g. sinusoidal, square etc. Some of them needs floating point multiply or look-up table etc. In this paper the digital quadrature oscillator with triangular output signal and amplitude stabilization is described. The quadrature output can be relevant for some applications. The output signal amplitude control is derived from state space equations. Moreover it is shown that for some values of control parameters behavior of the oscillator is chaotic.
