We have three DC 110V DC SERVO MOTOR EACH 8Kw.. The size of the motor is like 2HP Water pump motor. We need Servo 3 amplifier for the 3 Motors. Or any kind of of control like the Servo motor that does the following work: 1. Gives a 0 to 12 volt DC range to control the speed of the motor. 0 means stop. Then eventually 1, 2, 3, 4 etc will increase the speed to maximum. 2. Change direction of movement of the motor, Clock wise/ anti-Clock wise. We want complete circuit done and tested and sent to us. If it work, we will do the business in a regular order basis.

We seek original music compositions (be it instrumental or lyrical songs) to be submitted through our website. The composers of these independent music tracks must not be linked with any Collective Management Organisations (CMOs) internationally. I will give you a list of websites such as , , , etc in which you will be able to contact individual musicians one by one. It can be seen as a "spamming" job but I need you to contact only original and independent artistes. No popular cover songs allowed. Besides "spamming" them, it will be good if you can suggest ways on how to get to a load of independent musicians to come on board our website to submit their music. I would love to hear your ideas and explore together with you to do so. Although I will give
Design an amplifier with the following specs found in the attached sheet. Explain how you derived the resistor and capacitor values for the amplifier, and provide a spice model.
This project is based on homework that is due in about 12 hours. Designing analog amplifier using basic undergraduate level equations. I can do the pspice programming once the amplifier is designed, I am at loss as to how to design it however. If you can take this project I will pay you handsomely, should be only about 2-3 hours of work and I can pay up to $200 depending on the quality of the work provided and whether it matches the standards given (I can test it in pspice). If you are interested then message it to me.
The purpose of the driver section of the CPD board is to individually select the different system coils and to provide the distinction between transmit and receive modes on these coils by biasing PIN diodes located at the coils to either pass or prohibit the flow of RF energy. Pulsed drive signals (amplifier unblank signals) are directed to the various drive elements: Multicoils, TRs, DD, and body coil drivers as specified by the communications section of the CPD board. Additionally, open-circuit and short-circuit error detection signals (faults) for each of the drivers are stored in fault buffers which are read via select lines originating from the CPD microprocessor. The CPD board reports any faults to the remainder of the system where appropriate actions are taken. The mult...

I am making a simple arduino prototype and I need help designing a simple circuit to amplify the output (left channel only) from this adafruit breakout () for the VS1053B chip. The Arduino (a teensy 3.0 from ), VS1053 breakout board, and amplifier will all need to be powered by a 3.7V liPoly battery that I'm using now. I have little to know electrical knowledge, and I've been trying a lot of examples from the web without any luck. For reference, I've been using code from this project to get the rest of the circuit/software working: I've been able to get output working using headphones, but not as a line out signal.

...see file for amplifier overview There is a broadband amplifier board (used to read signals from a special kind of photodiode) which needs some additional components. Basically, a comparator which has an adjustable threshold must be added. The analog signal output as it is now has peaks from 0 to -1.5 V roughly, with a width of ~30 ns (negative pulses, kind of Gaussian shape). About 10^6 to 10^7 pulses come per second from the diode. The threshold should be adjustable from roughly -0.1 to -1.5 V using a potentiometer. The original design files are in P-CAD format, which must first be imported into Altium Designer (there is a way to do this, but it might not be completely automatic, I don't know). The comparator circuit must be designed and added to the ori...

I am building a bi-directional amplifier which would boost the signal of the transmitter & receiver . I have finished all the circuits but I still have issues related to the driver circuit for the SPDT Switch . The switch has a typical switching speed (Ton and Toff) <15nSec. The circuit driver for the switch that I have drawn has typical Fall/Rise 35nSec and it will turn on and off the switch within 50nSec as the author of the switch claims in their application notes. I need confirmation if this driver will turn on and off the switch within 50nSec and I need to know the delay between 2 control lines VC1 and VC2 . I have also draw another circuit driver that would also provide 35nSec for fall/Rise, but the delay between 2 control lines is about 120nSec. This is an...
