An amplifier will amplify a signal. For example, the antenna in a radio will receive an extremely weak signal; before it can be converted to a sound, it must be amplified (made stronger), by a factor of several million. Of course, since you can't produce energy out of nothing, an amplifier doesn't actually produce the energy for the strong version of the signal - it requires a power supply.
That's a pretty good question. In computers a change in voltage level is usually the data signal. There are many industrial applications where a change in current is used as a signal. In fact ANY change in voltage or current can be used. Data signals are very weak (high impedance) compared to power supply voltage and currents.
carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)
correctional signal
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
Weak signal depending upon the type of signal.
There is no signal in the area you are in.
I think it might be weak. I am not sure.
e350 is bad that's why
Yes.
You are too far from the router.
obtaining voltage gain of a weak signal
Error 9 on that particular changer is a weak RF signal error. That means that the unit is not sending out a strong enough signal to the antenna. Error 9 on that particular changer is a weak RF signal error. That means that the unit is not sending out a strong enough signal to the antenna.
You have a problem with your ground. A weak ground will always cause this type problem.
