two decision techniques (arg-decision and iq-decision) -> Explanation: Две методики решения (на основе анализа фазового угла (сигнала) и на основе анализа синфазной/активная и квадратурной/реактивной составляющих сигнала Здесь: arg (argument) - это (полярный) угол, т.е. фазовый угол сигнала по отношению к опорному/исходному сигналу а IQ - это In-phase and quadrature components = синфазная (активная) и квадратурная (реактивная) составляющие сигнала Principles of Lock-in Detection https://www.zhinst.com/others/en/resources/principles-of-loc... Signal mixing in the time domain ... Equation 7 is the demodulated signal and the main output of the lock-in amplifier: with the absolute value |Z| = R given as the root-mean-square amplitude of the signal and its argument arg(Z) = Θ given by the phase of the input signal relative to the reference signal.
