摘要: The quadricorrelator for a demodulator frequency-modulated signals has first input receiving an in-phase component of the signal and second quadrature signal. inputs are followed by respective multiplier units. output unit is connected with positive sign, negative sign to adder unit. supplied via transfer function unit, A characteristic formed between cuts frequency axis at point where nonzero runs essentially linearly in sufficiently wide band which surrounds or adjacent intersection point.
