How to Generate Fibonacci series of pulses if 1000Hz wave form was given.:smile:
 

Then the dutycycle of the waveform should be varied according to the fibonacci series (1,1,2,3,5,8..). Since the input frequency is 1000Hz, time period is 1/f = 1ms. If you consider a square wave with 50% dutycycle, it will be high for 500us and low for another 500us. So you need to create a pwm signal with variable dutycycle.
Now, ratio of the dutycyle of consecutive pulses should be of the form of fibonnaci series. For example, the dutycycle of the pulses should be
10%, 10%, 20%,30%,50%,80% keeping the time period constant. You can see the ratio of the pulse width or dutycycle is a fibonacci series. You can even implement the same starting with 1%,1%,2%,3%,5%,8%,13%,21%,34%,55%,89%.

Hope this helps..
