Brain freeze. How do I convert seconds to cycles equation wise? I have lost my proportion logic. :ashamed1:
 
What basis? 60 Hz?

if you want to convert cycles/sec to sec/cycle
just invert
if f = 10 cycle/sec
time = 1/10 = 0.10 sec/cycle

if on a 60 cyc/sec basis
divide by 60
1 cycle / 60 cyc/sec = 0.01667 Sec

60Hz. The raw values are specified in seconds, but the settings sheet wants cycles.

IE:

Zone 1 delay @ 0.05 seconds = 3 cycles

Zone 2 delay @ 0.35 seconds = to 21 cycles

Zone 3 delay @ 1.2 seconds = 72 cycles

And yes I am aware that Zone 1 has a 3 cycle delay :)

The simple way is to go by what you already know. That is seconds and cycles. You know that 1 second is 60 cycles. To get from 1 to 60 mathematically, you just multiply by 60, so seconds times 60 gives you the number of cycles.

No need to do repeating decimals or division.

Seconds x 60 = cycles

What if I be in Spain or Austria?

If there is ever a moment for this >>> :slaphead::slaphead: x60 would be a lot easier... I tend to think it out the most complex... often till mental exhaustion. :lol: :(
 
Period (t) is the mathematical reciprocal of frequency (f). 1/t = f, 1/f = t
 
K8MHZ said:
So, if t= 1 second, then f would = 1/1, or 1?

I know what you are getting at, but as presented, the above question begs to be asked.

The question begs to be answered:
Yes. A frequency of one Hz has a period of one second
Not surprising at all to me.

I am playing the Devil's advocate here.

The question asked was:

"How do I convert seconds to cycles equation wise?"

This

"Period (t) is the mathematical reciprocal of frequency (f). 1/t = f, 1/f = t"

being the answer, IMHO, isn't the answer to the question.

It is indeed a fact, but is it the answer to the question?

The OP was looking for a number of cycles, not a frequency, based on a known amount of time.

Looking back at the exact wording of your example, the correct answer would be that if t = 1 second, then f would be 1/second or one per second. Not just 1.

And the formula given was a legitimate answer to an intermediate post even though it did not directly answer the OP's question.

If the time period in question is, for example, .2 seconds, and you have a frequency of 10 Hz (cycles per second), then the number of cycles would be:

.2 seconds times 10 cycles per second, equals 2 cycles.

When dealing with frequency and rotational speed, we often leave out the "cycles" or "rotations" dimension, since it is technically a dimensionless number, but that makes it harder to check that you got a correct formula.
 
K8MHZ said:
Agreed, but there is no multiplication in these formulas:

1/t = f, 1/f = t

Your example,

.2 seconds times 10 cycles per second, equals 2 cycles,

is:

t(time) x f (cycles per second) = x (number of cycles)

not:

1/t = f, nor 1/f = t

As I stated, the formulas you reacted to were just an intermediate result, not the final answer.
If they were intended as a direct answer to the OP, then, yes, they were not adequate.

I see that now. The correct answer is "multiply time by the frequency". Example 10 seconds at 60 cycles/sec => (10 sec)(60 cycles/sec) = 600 cycles. I'm sure someone else must have said that.
