Amplitude of
a signal is
the value of
the signal at
any point on
the
wave
It
is equal to the vertical distance from a given point on the wave form
to
the horizontal axis
The
maximum amplitude of the sine wave is equal to the highest value
it
reaches on the vertical axis Amplitude
measured in Volts, Amperes or Watts
Period & Frequency
|
Period: Amount
of time (
in seconds) a
signal need to
complete one
cycle
Frequency:
Number of cycles completed in one second
Unit
of Period: Period is expressed in seconds
|
Communication
industry uses 5 units to measure period
Frequency
is measured in hertz, There are 5 units used in Hertz
|
Seconds____Hertz
Milliseconds____Kilohertz
Microseconds____Megahertz
Nanoseconds____Gigahertz
Picoseconds____Terahertz
