Ultrasonic burst signal from
Trigger Pulse
The vibration and amplified
waveform according to
transmitting and receiving of
ultrasonic signal.
Masking signal(Internal) to remove
the first received internal crosstalk
signal.
Amplified signals only for the
reflected(received) signals
Converting received signal to
digital form (signal)
Time pulse proportional to the
distance of wave that reflected
first(proximal object)
Preset limitation of distance
window(Preset range).
Filtering the signal in which only
entered window limit
Sample / Hold; converting the
approach signal to continuous
signal.
