 Jitu said: (Sep 26, 2011) f=1/T so that 1/1.25micro sec = 0.8Mhz

 Vivek said: (Aug 23, 2012) By the formula of frequency we can find the frequency of clock waveform. Time period(t)is given of that waveform is=1.25microseconds f=1/t Where T is the time taken by the clock waveform. f=(1/1.25) And f=0.8mhz

 Sagar said: (Dec 14, 2013) 1.25us = 125x10^-8 sec. Thus, 1/T = f. Hence, f = 1/125x10^-8 sec. f = 800kHz = 0.8MHz.

 Ananya said: (Aug 4, 2014) Just 1/1.25 * 10^-6 = 10^6 * 100/ 125 = 0.8 MHz.

 Shashank said: (Jun 16, 2015) = 100/125*10^-8. = (4/5)*10^6. = (0.8)*10^6. = (0.8)*10^6. = 8 MHZ.
