After generating the signal on the first rising edge, the controller should check whether the second rising edge is within the limits i.e. (not less than 100ms). Only after that, signal will be generated by the controller.
Regarding 15us, as this was for avoiding false triggering, I am going to...
I have to generate a signal on every rising edge. Regarding integer frequency, I meant that if I am generating the required signal on every rising edge what if the input trigger pulse frequency changes from 10Hz to 20Hz (i.e. from 100ms to 50ms). What check should be done in order to generate...
I have been using PIC18 micro-controller for generating reference signal and a charging signal at 100 Hz rate max. Now I have to generate this charging signal after sensing an external trigger pulse of width 15us with frequency in between 1 to 100 Hz. I am using 4 timers of PIC18 for different...
There are no exponential rise and fall when the pulse is slow but as the delay time is increased to above 100uS then this exponential rise is seen on oscilloscope.
I am generating 300us Monostable Pulse through 555 IC with 12V Vcc supply.The frequency is 5Hz. The pulse width is ok but when I see the waveform on the oscilloscope, the pulse shape is not good. The pulse rises to 10V very fast but after that exponentially goes to 11V and while discharging it...
hi all,
I am trying to simulate a push pull stage with negative feedback to op amp. i shall be using it to drive a dc motor with ratings of 10V and 0.5A.
Awhile simulating, sometimes(keep in mind) there are oscillation in output of op amp and hence at the load. I have tried changing Vsource...
hi all
i want to design smps with variable output from 1V to 50V. i have seen on the net how to select the circuit element(inductor capacitor) for fixed output. BUT since i have to vary the duty cycle in order to have variable DC, i dont understand how to find the circuit element values.
Re: microcontroller problem
i am talking about the case when we are not using watch dog timer.
if controller hangs in an indefinite loop then we can't do nothing but what about unprogrammed area or NOP area.
so the controller design is such that even if it gets stuck in unprogrammed area the...
micro controller problem
hi everyone
i want to know what actually happens inside the controller when micro controller hangs.
if micro controller jumps to unprogrammed area (by any problem) then will program counter revert back to the reset value after traversing to all the nop instructions...
pi controller
hi all i want to calculate the values of Kp, Ki for the PI controller. what are the methods.
also i want to know whether PI is a special case of IIR. if yes what are the assumptions or conditions.
