Illustration of the asynchronous stimulation protocol for a two-channel stimulation scenario, where IPI, F, P, PW, A and CH indicate inter-pulse interval, frequency, pulse, pulse width, amplitude and stimulation channel, respectively. The H-bridge outputs a multiplexed signal that is demultiplexed to the respective stimulation channels. All paremeters (IPI, F, PW and A) are equal before and after demultiplexing. The horizontal lines represents time, where the dotted horizontal segments indicate prolonged duration. The green and blue color indicate the blanking intervals, where the green color indicates blanking duration calculated from Eq. 1 or the first term within the brackets of Eq. 2 and the blue color indicates blanking duration calculated from the second term within the brackets of Eq. 2
