Most often inductors are used to block AC or high frequency signals. This is the dual of what capacitors do which is pass AC or high frequency signals. The precise definition of what is high frequency is a bit loose and depends on the circuit values.
I am 50 and have been in menopause for about 14 months. Since April of last year, I have experienced periods of INTENSE hot flashes and night sweats - sometimes 30 within 24 hours! These periods last 6-8 weeks and then the hot flashes reduce in intensity and occurance gradually over the next 10 weeks. Then, unfortunately, they start again.
(Most were 45 to 49.) Hot flush duration was approximately 8 years for this group compared to less than 4 years when onset occurred at ages 50 years or older. Bottom line: The earlier you begin to have hot flashes (even if you are still getting your period) the longer you can expect them to continue during menopause. Now that you have this information, discuss therapies with your doctor.
