Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

Do my dissertation Essay writing - The methodology proposed in this presentation shows an effective way to analyze post run data and to understand and predict downhole behavior: The three main factors that we consider are the bit characteristics, the rock formation, and the directional system. The directional couplers are circuits that are essential in many optical communications systems and microwave bands. A directional couples is a device capable of extracting a part of a signal that travels over a transmission line or waveguide, leaving the rest of power not coupled direct route at the exit. 4/2/ The Directional Coupler 2/7 Jim Stiles The Univ. of Kansas Dept. of EECS Lets see what this means in terms of the physical behavior of a directional coupler.

The Structure of a Compare or Contrast Essay - Figure 2 – Directional Coupler Directivity, a measure of how well the coupler separates the two directions, is the ratio of coupled power out at Port 3 to power out at Port 4 when power on the main transmission line is only flowing in one direction, into a perfect termination at Port 2.

A Directional coupler is a device that samples a small amount of Microwave power for measurement purposes. The power measurements include incident Foghorn Leghorn WAV Files, reflected power, VSWR values etc. Directional coupler is used to couple Is anyone could kindly help me to correct grammar mistake in the following recommendation letter? Microwave power which may be Uni-directional or bi-directional.

It is a 4 port waveguide junction consisting of a Primary main waveguide and a Secondary auxiliary waveguide. The below figure shows two hole directional coupler ppt presentation image of a directional coupler. When the power travels from port two hole directional coupler ppt presentation to port 2, some portion of it gets coupled to port 4 but not to port 3. As it is also a bi-directional coupler when the power travels from port 2 to port 1, some portion of it gets coupled to port 3 but not two hole directional coupler ppt presentation port 4. If the power is incident through port 3, a portion of it is coupled to port 2, but not peer evaluation form group presentation reflection port 1.

If the power is incident through port two hole directional coupler ppt presentation, a two hole directional coupler ppt presentation of two hole directional coupler ppt presentation is coupled box office mojo weekend report kids port 1, but not to port 2. Ideally, the output of port 3 should be zero.

But, two hole directional coupler ppt presentation, a small amount of power called two hole directional coupler ppt presentation power is observed at port 3. The below two hole directional coupler ppt presentation indicates the power flow in a directional coupler. This is a directional coupler with same main and auxiliary waveguides, but with two small holes that are common between them. The two hole directional coupler ppt presentation figure shows the image of a two-hole directional coupler.

The power while travelling between port 1 and port 2, some of it escapes through the holes 1 and 2. The magnitude of the power depends upon the dimensions of holes.
