Hi Bob, Yes! And that's all the more reason I encourage people that design hobby prototypes or commercial products to treat precise time with some dignity and respect. Embrace the challenge. There is no reason that the leading edge, pulse width and trailing edge, or the rise time, fall time and impedance can't be implemented with precision.
True, some devices fail this obvious goal but it's best to use those as repulsive examples to avoid rather than attractive examples to follow. /tvb ----- Original Message ----- From: Bob Stewart To: Tom Van Baak ; Discussion of precise time and frequency measurement Sent: Wednesday, November 09, 2016 3:28 PM Subject: Re: [time-nuts] How to get PPS from ublox mini-PCI GPS to APU2 SoCserial port for ntpd Tom, How many times have people posted here, on time-nuts, not to trust the trailing edge of a 1PPS pulse?
