Determine the period of each of the following discrete-time signals (if a signal is not periodic, denote its period by infinity)
a) cos(2pi0.15n)
b) cos(2n);
c) cos(pi0.3n) + cos(pi0.4n).
Answer:
a) it is periodic
N = (20/3)k = 20 { for K =3}
b) it is Non-Periodic.
N = ∞
c) x(n) is periodic
N = LCM ( 5, 20 )
Explanation:
We know that In Discrete time system, complex exponentials and sinusoidal signals are periodic only when ( 2π/w₀) ratio is a rational number.
then the period of the signal is given as
N = ( 2π/w₀)K
k is least integer for which N is also integer
Now, if x(n) = x1(n) + x2(n) and if x1(n) and x2(n) are periodic then x(n) will also be periodic; given N = LCM of N1 and N2
now
a) cos(2π(0.15)n)
w₀ = 2π(0.15)
Now, 2π/w₀ = 2π/2π(0.15) = 1/(0.15) = 1×20 / ( 0.15×20) = 20/3
so, it is periodic
N = (20/3)k = 20 { for K =3}
b) cos(2n);
w₀ = 2
Now, 2π/w₀ = 2π/2) = π
so, it is Non-Periodic.
N = ∞
c) cos(π0.3n) + cos(π0.4n)
x(n) = x1(n) + x2(n)
x1(n) = cos(π0.3n)
x2(n) = cos(π0.4n)
so
w₀ = π0.3
2π/w₀ = 2π/π0.3 = 2/0.3 = ( 2×10)/(0.3×10) = 20/3
∴ N1 = 20
AND
w₀ = π0.4
2π/w₀ = 2π/π0. = 2/0.4 = ( 2×10)/(0.4×10) = 20/4 = 5
∴ N² = 5
so, x(n) is periodic
N = LCM ( 5, 20 )
An NMOS transistor with kn = 1mA/V2 and Vt = 1V is operated with VGS = 2.5V. At what value of VDS does the transistor enter the saturation region? What value of ID is obtained in saturation?
Answer:
a) the point at which the transistor enters the saturation region is 1.5 v
b) the value of ID is obtained in saturation is 1.125 mA
Explanation:
Given the data in the question;
for an NMOS, the condition for the saturation is;
V_DS ≥ V_GS - V_t
V_GS is 2.5 v and V_t is 1 v
so we substitute
V_DS ≥ 2.5 - 1
V_DS = 1.5 v
so the point at which the transistor enters the saturation region is 1.5 v
The drain current I_d in the saturation region;
I_d = 1/2×μₙ×Cₐₓ×W/L×( V_GS - V_t)²
= 1/2Kₙ ( V_GS - V_t)²
our Kₙ is 1 mA/V², V_GS is 2.5v and V_t is 1 v
so we substitute
I_d = 1/2(1 mA/V²)( 2.5 - 1 )²
= 1/2(1 mA/V²)( 2.25)
= 1.125 mA
therefore, the value of ID is obtained in saturation is 1.125 mA
A plant might be emitting some dangerous pollutants that are environmentally harmful, but completely eliminating them would be so expensive that the plant would have to close, throwing many local inhabitants out of work. Assuming there is an obligation both to preserve jobs and to protect the environment. What is the best technique that should be used to resolve this problem?
Select one:
a. The convergence and divergence techniques
b. The Utilitarian approach
c. The creative middle way
d. The line drawing technique
Answer: c. The creative middle way
Explanation:
As there is both an obligation to preserve jobs and to protect the environment, a creative middle way which involves compromise would be most effective.
The company involved should process and remove the worst pollutants alone while leaving others so that the process will not be so expensive that they have to close down.
They will do this till a better and more environmentally beneficial solution can be found at which point they can then clean up the previous pollutants with the hope that they have not irrecoverably damaged the environment.

Ordan has _ 5 8 can of green paint and _ 3 6 can of blue paint. If the cans are the same size, does Jordan have more green paint or blue paint? Explain.
Answer:
Jordan has more green paints
Explanation:
Given
[tex]Green = \frac{5}{8}[/tex]
[tex]Blue = \frac{3}{6}[/tex]
Required
Which paint does he have more?
For better understanding, it's better to convert both measurements to decimal.
For the green paint:
[tex]Green = \frac{5}{8}[/tex]
[tex]Green = 0.625[/tex]
For the blue paint:
[tex]Blue = \frac{3}{6}[/tex]
[tex]Blue = 0.5[/tex]
By comparison:
[tex]0.625 > 0.5[/tex]
This means that Jordan has more green paints

Examine Figure 1 – what does it “look like”? Zoom in. Take the FFT of x and explain what you see.
Manipulate the FFT and perform the IFFT to create a signal which is a continuous (i.e. no interpolating zeroes) sinusoid in the “time” domain. Explain the amplitude of the sinusoid.
The amplitude of the sinusoid is 28384 *x soít cos.
What is amplitude?Amplitude is defined as the greatest deviation from equilibrium of a point on a vibrating body or wave in terms of displacement or distance traveled. In most cases, amplitude is calculated by looking at a wave graph and determining the height of the wave from rest. The strength or intensity of the wave is gauged by its amplitude.
Sinusoid is defined as a signal with sine wave characteristics. In the liver, spleen, and bone marrow, sinusoids and irregular tubules transport blood in place of venules and capillaries. The sine or cosine functions from trigonometry form the foundation of sinusoidal signals, which are periodic functions.
Thus the amplitude of the sinusoid is 28384 *x soít cos.

In the context of electronics, the term "ground" is often used to refer to:
1: the negative battery terminal
2:the breadboard
3:the circuit diagram
4:the components
Which one is the answer
Answer:
1: the negative battery terminal
Explanation:
When we design and develop an electrical circuit in electrical and electronics engineering, it is important that we define a reference point for all electronic signals from which we can measure voltage. Although, the voltage passing through a reference point in an electrical circuit is typically 0 Volts.
Also, a ground is a common return path in an electrical circuit for the current flowing through the circuit.
When working on a direct current (DC) circuit that is mainly operated using a battery, the negative terminal of the battery would be the ground (reference point) for all the components connected to the electrical circuit.
Hence, in the context of electronics, the term "ground" is often used to refer to the negative battery terminal.
