What was jkcet cuttoff?
In a class A amplifier, the base/emitter (B/E) junction will be forward biased. In a class B amplifier, the B/E junction will be biased to the point of cuttoff (About +700mV in an NPN/silicon device. In a class C amplifier the B/E junction will be biased below cuttoff The Base Collector junction is reverse biased in all cases, but not to exceed the rated maximum C/B voltage for the device.
firstly you will need a solar cell 3V to power your electronic bell .after that you can make a 5Khz sine wave geneartor and connect it to solar cell and you should also use a timing and control circuit to cuttoff the bell after some time and when any one press the switch circuit energies and take the power from solar cell and alarm will start.
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY firstname.lastname@example.org
Monitor BMI (body mass index) to determine the body fat levels. It is possible to have a BMI that is too low and excessive cardio workouts could be part of that. Many gyms can perform BMI tests, but don't trust the ones where you just stand on a scale and they look on a chart. That does not consider how muscular a person is. When I stand on a scale and look at a chart…
