Depends on who made it.
It depends on the size of it..What is the barrel length?..Is it bronze?..more f
Telegraph, signal flags, courriers, drums, and cannon shots were used.
electricity and a signal
yes
a cannon would signal the start of the play because it was so loud it would get everyones attention, to watch the play. :)
Small signal amplifier is needed because it is used for amplifying input signals having low frequency or amplitude.
to calculate and measure the impedance ,admittance is simple
train by learning morse code, using signal flags, signal lamps,blinkers,flashlights, semaphore or hand signaling
To answer this properly more context is needed but frequency is in most contexts continuous.
Because the number you see is your tv tuning to that frequency if there is no signal than try replacing your cable ends or if needed the whole line it is cheap
The signal between Jen and Luke was a tap on the shoulder. They agreed that if one of them tapped the other on the shoulder during the meeting, it meant they needed to leave urgently.
A; BUFFER is used for isolation, translation of levels and amplification if needed
