How can you fix a turn signal that won't automatically turn off unless you make a greater than ninety degree turn?
you need to replace what is called a " turn signal cancel cam ", it is locaTED IN THE COLUMN so depending on what kind of vehicle you have , it may require specialty tools.
Why is it desirable to have the modulation index of an am signal as large as possible without overmodulation?
http://hertenberger.co.za/?p=420 Talk Radio 702 is available on both 106 FM and 92.7 FM If you are in the greater Tshwane area, Midrand, or northern Joburg, the 106 signal is probably better for you, while 92.7 covers the greater Joburg area. Wherever you are, take the time to check and listen, to see whether 106 or 92.7 is best for you. If your car radio is RDS enabled it will display "Talk 702" and will automatically…
Modulation index(m) is given by the formula (|x(t)max|)/v, where x(t) is the modulating signal and v is the maximum carrier voltage. so m will be greater then 1 if x(t) is greater then v. This results in overlapping of upper and lower wave in the output signal which is called diagonal clipping and this information is lost and thus greater value of m is undesirable.
What is the difference between a floating output signal generator and a grounded output signal generator?
A signal generator can be used to function in two ways. In high frequencies, one of output probes of any generator (negative probe) will be grounded automatically, hence it has to be connected with grounded parts of other elements not to create a short circuit problem. But, in the case of floating type (f<100 Hz, generally) probes of the signal generator is not grounded.
Why should be the voltage of the modulating signal greater than that of the carriers in the nonlinear modulators?
When the modulating signal is greater than the carrier it can cause over modulation, that will cut of the peaks of the modulating signal and when detected by the receiver the final audio signal will also show the flat peaks and the results will be a distorted sound at the speaker. A 90% modulation is always better than a 100% modulation. In the case of frequency modulation it will cause the frequency to shift to…
Your cell phone does it automatically. Your phone will switch towers automatically but if your cell company's tower is not the strongest signal you will be using another company's tower and be charged roaming fees. You have to call customer service and get the code your company uses to lock on to your closest home tower.
