@coquelicot: I meant that the signal won't be used to consume a substantial amount of power. The signal will be interpreted by a MCU. (more) |

@Lundin: I would connect the slow signal at the gate, and the fast signal (from 555) at the source. I would use the NE555 (TI). That should work, right? (more) |

@coquelicot: apologies, I fixed the link, now it should be clear. The modulated signel will be just used for communication to another device and has negligible loads. (more) |

| Question | — |
555 timer, PAM with digital signal I'd like to use a 555 timer as carrier wave generator at 50 kHz and modulate the amplitude with an external digital signal at 1 kHz. The pulse width remains constant at 10us (50% duty cycle). Do you suggest to add MOSFET on the OUT pin of 555 timer, or can I connect the signal directly to a ... (more) |
