Abstract
It is described a modulator apparatus () comprising: an input terminal () structured to receive an analog electrical signal (x(t)) having an information content to be transmitted; a loop filter structured to receive an error signal (ε(t) and provide a filtered signal (s(t)), the loop filter being configured to minimize said error signal (ε(t)); a modulator device () configured to module the filtered signal (s(t)) and provide a Pulse Width Modulated, PWM, signal (y(t)) to be transmitted including a plurality of pulses having corresponding widths correlated to non-quantized amplitudes of the filtered signal (s(t)); a first pulse width demodulator () configured to receive the PWM, signal (y(t)) and provide a demodulated signal (ŝ(t)) and a difference module () configured to receive the analog electrical signal (x(t)) and the demodulated signal (ŝ(t)) and provide the error signal (ε(t)).
