Voltage amplifier designงาน

I want to know 1. Compute the generalized constants [A], [B], [c], [d] for all series components, α, β, γ, δ, ε, ζ, η. 2. Implement the forward and backward sweeps, and compute the three-phase line-neutral voltages for all nodes, 1, 2, 3, 4, 5, 6, 7, 8. Set Tol = 0.01%, i.e. for every line-to-neutral voltage of every node, the magnitude change compared to the last iteration is less than 0.01%. 3. Suppose node 7 is the load center. Find tap positions Tapa, Tapb, Tapc for the voltage regulator δ, which can bring all three line-to-neutral voltages of node 7 to the range of 119V and 121V on the 120V basis. (Equivalently, to the range of 2380V and 2420V on the 2400V basis.) 4. When the regulator δ is operated at the tap positio...

Hello, I am an Kevin, an engineer based in the UK. I am designing an amplifier that is powered by a PC power supply (12V DC). PC power supplies generate a lot of electrical noise so I want someone to design a device that eliminates the noise so that no hissing, cracking etc can be heard on the amplifier i.e. CLEAN DC. The device must be cheap to make and use PCB mount components. Thanks.

The application is for a RF synthesizer to create a variable frequency output signal which is connected to a RF power amplifier driving a Tesla coil whose load has variable characteristics depending on temperature and humidity. To hit peak resonance of the Tesla coil the driving frequency has to be continuously changed. We can look at the reflected power and produce an error signal, but we need this error signal to control a clean variable frequency source so we always hit peak resonance of the Tesla coil. The frequency range is 25-31MHz, step size around 10kHz. LMX2572LP device is preferred.

Hello, I am designing a detector to count the passing of spokes on small wheels. My plan is to use a light source like an LED and a receiver like a photo-diode to create a sort of break beam setup. The signal will be sent through an amplifier with filtering, to the mic input of a PC to be used for measuring the passes per hour of the spoke of the wheel. I am having a hard time finding the right product combination and circuit to make this happen. The wheels are suspended so the spoke casts a shadow on the collector to trigger the signal as the wheel rotates / oscillates. The wheels range in sizes from 8mm to 20mm and have spokes from 1mm to 2.5mm wide. This should be a very simple device to build and I have made some but it is hard to get both a signal that has enough gain ...

Therefore, I need a design in which I can change the type of cells(monocrystalline or polycrystalline), all coefficients of temp., voltage and current. As a result, I should be able to see that how the efficiency of solar panels has dropped over the period of time. You will also create a separate word file for me where you have to briefly explain all the steps that how you designed it and how the simulation works. In case, If you know of any other software that can simulate the efficiency drop of solar panels, let me know.

...is not related to embedded programming. The task is to implement the algorithm on desktop using python with an eye on implementing the same in embedded. What this means is that the freelancer should not be using heavy computation methods and libraries (like PyTorch) that may not be available in the embedded domain. The samples are coming in at the rate of 10 Hz. The samples are measuring the voltage of a vehicle battery. The samples are also measuring the accelerometer input on 3 axes. Using the above samples, we need to tell with certainty whether the ignition of the vehicle turned ON or turned OFF. It is OK to use 2 separate Peak detection algorithms with different parameters to determine whether the ignition turned ON or the ignition turned OFF. The peak detection alogrithm ...
