The peak frequency deviation, minimum bandwidth, and baud for a binary FSK signal for the given frequencies are respectively;
a) 0.5 kHz
b) 9 kHz
c) 4000
<h3>Peak frequency deviation</h3>
1) The peak frequency deviation is gotten from the formula;
∆f = |f_m - f_s|/f_b
where;
Thus;
∆f = |38 - 40|/4
∆f = 0.5 kHz
2) The minimum bandwidth is given by the formula;
B = 2(∆f + f_b)
B = 2(0.5 + 4)
B = 9 kHz
3) For FSK signal, N = 1, and the baud is gotten from the Equation;
baud = f_b/1
f_b = 4 kbps = 4000 bps
Thus; baud = 4000/1 = 4000

Answer:
The value of poisson's ratio of the material = 0.28
Explanation:
Given data
Force F = 15700 N
Diameter D = 8 mm
Change in diameter ΔD = 0.005 mm
Modulus of elasticity E = 140 × M Pa.
Stress induced in the shaft due to applied force
Area A =
⇒ A = = 50.24
Now stress
⇒ Stress = 312.5 M pa ------ (1)
Now strain in the element is given by
∈
⇒ ∈ =
⇒ Strain ∈ = 2.232 ×
We know that poisson's ratio is given by
⇒
Change in diameter ΔD = 0.005 mm
Diameter D = 8 mm
Strain ∈ = 2.232 ×
⇒
⇒ 0.28
This is the value of poisson's ratio of the material.
Answer:
The kinetic energy is 6.4 kJ and the distance traveled by the system is 256 m.
Explanation:
Given the mass of the system is 8 kg.
And initially, it moves with a velocity 40 m/s.
Also, it experiences 25 N force which opposes its motion.
We need to find the kinetic energy and the distance traveled by the system before going to rest.
It will be the kinetic energy of 8 kg mass with 40 m/s velocity that is transferred to work.
Since this system is opposed by 25 N force, work done by the force will be.
And the kinetic energy transferred to work. We can equate them.
So, the system will travel 256 m.
