Pulse Meter Design! help with 555 timer! Circuit attached!
I have to design the digital part of a pulse meter.
The output from th analog comparator is a pulse with amplitude of 4.895V and Frequency 16.108Hz.
This pulse is then fed into a D flip-flop and gated with a 555 timer circuit with a 1KHz frequency.
I need to simulate the above but cannot find a suitable simulator which has the LM555. I am using Tina simulator, though it has the LM555, its not working as expected. Please note: R1 = R2 = 1KOhms and C=481nF..though i should use practically available components, I want to see the output of the circuit in simulation first and then go on to PCB design.
Please please please advise if there is a need to change component values or any alternative simulators.
Thanx much!
