ummm 100?

jack1 · Answer

i dunno, is it?
htz is per second, so 100 kHz is 100000/second...yeah?
so i thought that 100ms = 0.1 sec
so 100000 x 0.1 = 10,000 pulses?
but i wasn't sure, can anyone help plz?

sorry

ganeshie8 · Answer

Time period of each cylce,   $\large  T   =  \frac{1}{f} =   10^{-5}$ seconds

ganeshie8 · Answer

just count how many time periods are there in 100ms

ganeshie8 · Answer

number of cycles  =   $\large  \frac{100 \times 10^{-3}}{10^{-5}}$

jack1 · Answer

100/10^-5 = 10,000,000?

jack1 · Answer

ah, gotcha, my bad 0.1/10^-5

ganeshie8 · Answer

or another way to look at it is :

1s  ----->   100k cycles
100ms -----> ? cycles

jack1 · Answer

10% so 10,000
cheers man, wasn't sure if there was anything special about counting them differently bcoz they are pulse waveforms... s'all
