Answer:
Scientists observe the world, while engineers focus on creating. While both fields do involve observation and analysis, engineering mainly deals with creating and working on already existing creations, while scientists work with things in nature.
Answer:
Explanation:
Given that:
x(t) = 10 sin(10t) . sin (15t)
the objective is to find the power and the rms value of the following signal square.
Recall that:
sin (A + B) + sin(A - B) = 2 sin A.cos B
x(t) = 10 sin(15t) . cos (10t)
x(t) = 5(2 sin (15t). cos (10t))
x(t) = 5 × ( sin (15t + 10t) + sin (15t-10t)
x(t) = 5sin(25 t) + 5 sin (5t)
From the knowledge of sinusoidial signal Asin (ωt), Power can be expressed as:
For the number of sinosoidial signals;
Power can be expressed as:
As such,
For x(t), Power 
For the number of sinosoidial signals;
For x(t), the RMS value is as follows:
No thx but have a great day and god bless u :-)
Answer:
120 Hz
Explanation:
Given that a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, what will be the output frequency ?
Ideally, the supply frequency will be equal to the ripple frequency.
But in a half - way rectifier, the out put frequency is twice the input sinusoidal voltage frequency.
The output frequency = 2 × 60
Output frequency = 120 Hz
Therefore, When a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, the output frequency is 120 Hz.
The fact that an intra LATA call connects subscribers within the same LATA proves the PSTN architecture's correctness.
<h3>What does intra Lata mean?</h3>
- Calls placed using the Local Toll Service (also known as IntraLATA Toll, Local Long Distance, or Regional Toll Service) are placed inside of the Local Access and Transport Area.
- Calling a phone within the same LATA IntraLATA is the term for local phone service. An intraLATA call is one that travels from one LATA to another, either within the same state or between states.
- The customer is charged for intra-LATA calls made to uninteresting neighboring towns. A LATA, which denotes local phone service, is made up of geographical areas.
- Local Access and Transport Area, or LATA, is a three digit (5 in Florida) code that designates a particular geographic market where calls are forwarded.
