Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.Zatrudnij użytkownika Electrical Engineers

Hi We are looking to develop a simple communication Module. We want to Use LORA RA02 which should be communicating in 1 : N using a PIC micro controller. In the sense the Lora RA02 should be addressable and each Lora should be able to communicate with each other. Preffered Microcontroller would be PIC24FJ256GA702 or PIC 18F4520 . We would be requiring the programme and Circuit Layout.
Design an air-filled rectangular waveguide (a = 2b) such that its dominant mode is at ‘frequency’ with length = 2λ and wall thicknesses of 0.2 mm Examine the first 5 modes in the designed guide. Plot: 1. S11 / S21 (all modes in one plot) and specify the insertion loss for each mode. 2. The phase constant of these modes and determine the degenerate and non-degenerate modes. 3. Fi...
Buna ziua ! Caut un student, care este la ETTI si stie cu ce se mananca "CCEP"(sem 1), care face parte din Departamentul Bazele Electronicii. Am nevoie sa ma ajute la cateva probleme.
I need this research paper replicated with the same plot as can be seen in figure 7 of the research paper attached. It should be coded in MATLAB as has been done in the paper. Also, when replicating the results of figure 7- the x axis and y axis should have the same exact order as in the research paper.
We need help in physics project. 4f imaging configuration is used. We are looking for someone with physics background to help us with coding the problem using Matlab. Budget/timing/details can be discussed later
