Video capture card is a device, which is used to converting analog video signal to digital form
Self explanatory.. Don't use strikes?
Use iWeb. It is a pretty self-explanatory.
A pulse width modulated signal would be very useful in a switching power supply. This is but one example. Note, however, that there are better examples than the 555 for use in a switching power supply.
Self-explanatory really - it allows you, the user, to choose what colour you want to use !
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.

Well to annotate something is to make critical and explanatory notes of the work. This means to basically mark up the text. So to annotate a photo or a document you would take note on (or mark) the use of color, the texture, technique and so on.
You will have signal degradation unless you use the amplifier.
UNITY GAIN means there is no "gain" and no "loss" of the signal strength or integrity. It means your device has made use of the signal to enable it to function, but has not degraded the signal in any way. This means the signal coming out is as good as the signal going in and can be passed on to another piece of equipment to make it function. Note that the equipment up line has to be switched on or in standby mode to enable this function in equipment connected downstream from it.
These are two separate circuits. They use separate flasher relays. They use separate fuses. They use separate switches. Check your signal fuse and signal flasher relay.
