Answer:
Using Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common-carrier frequency.
Explanation:
- In SSB modulators, we pre-process a real signal by Hilbert Transform filter to form another real signal
- The signal has the same spectral amplitude but has 90° phase shift at each frequency relative to its input signal.
- The ordered pair gets almost all of its negative components cancelled
- thus, with the use of Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common carrier frequency.
Answer:
Total change in energy = 31 KJ.
Explanation:
Mass m=25 kg
Height h = 1 m
Initial velocity = 0
Final velocity = 50 m/s
Energy at initial condition
Energy at final condition
So the change in energy = 31250 -250 J
The total change in energy = 31000 J
Toxic is the answer, toxic meaning may cause death or other health problems.
Gas turbines extract the energy from combustion gas
and heat engines convert thermal and chemical energy to mechanical energy
gas is considered a chemical so i'm pretty sure it is considered one
