Answer:
Explanation:
The frequency components in the message signal are
f1 = 100Hz, f2 = 200Hz and f3 = 400Hz
When amplitude modulated with a carrier signal of frequency fc = 100kHz
Generates the following frequency components
Lower side band
Carrier frequency 100kHz
Upper side band
After passing through the SSB filter that filters the lower side band, the transmitted frequency component will be
At the receive these are mixed (superheterodyned) with local ocillator frequency whichh is 100.02KHz, the output frequencies will be
After passing through the SSB filter that filters the higher side band, the transmitted frequency component will be
At the receive these are mixed (superheterodyned) with local oscillator frequency which is 100.02KHz, and then fed to the detector whose output frequencies will be
Answer:
Explanation:
We understand that the sum of the pressures in the tank and the pump is equal to that of the Nozzle,
In this way,
For the pressure we also know that it is given by
So,
Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure
Area of the cylinder=πd²/4
Hence diameter of cylinder 14.27 mm
