    5 V pulse board stm32f407

    http://amarkham.com/?p=12 This URL spitted out by google seems really helpful regarding timers in STM32 Try the sample program there. Also do specify other data like Pulse width, and periodicity of the output pulse that will help us to help you further

    want CT scan images of lungs

    Subhasri, If there is any high profile scan centres near your locality pay a visit to them. Or check the medical encyclopedia they are sure to have these Mate she is planning to implement some image processing stuff on the CT scan image using Matlab / Labview at the most. I think that is...

    [SOLVED] why we divide 8051 timer by 12 ?

    8051 machine cycle consists of 12 clock pulses so we divide the crystal frequency by 12 This image explains the concept of instruction cycles and clock frequency

    How to create or open workspace in eclipse editor ?

    Mate the image tells us the location at which your new project is going to be created. If that is your first workspace then there is no need to worry about this and just select a location and click OK In the new window select File---> New--> <whatever you want to create> and start your project

    how to send a binary text file from pc to fpga board using matlab?

    Its better to go through the information given in Mathworks site https://blogs.mathworks.com/loren/2013/04/11/matlab-to-fpga-using-hdl-codertm/ Check the blog and if you have any difficulties do post on here

    P-Type JFET confusion

    Drain Source interchanging can alter the response curve in the case of an IC I need to work on this to be of more help to you But for design in paper they can work really cool But I seriously doubt this in practical ckt

    P-Type JFET confusion

    http://www.physics.csbsju.edu/trace/pFET.CC.html The drain current achieves negative maximum for Vgs=0 PS: Sorry for the error previously

    AM transmitter antenna problem..

    The second amplifier is a multi stage amplifier If the gain of the first system is A and the gain of second stage is B then the effective gain of the second system is AB Thus the second one has higher gain cause of multi staging the first one is a simple single stage amplifier and in...

    P-Type JFET confusion

    When it is grounded it does not effectively get turned off A Ptype JFET gets turned off only when a negative voltage is applied There is a reverse bias but this is not sufficient to pinch off the drain current So effective drain current exists when the gate is left grounded Vgs=Vs-Vg =...

    Cmos pmos and nmos

    Static power disipation in a CMOS can ruin other devices related to the CMOS in actual circuitory But still how are we able to see so many applications of it in real time

    P-Type JFET confusion

    Gradual rise is due to charging of internal capacitors of the JFET Partial conduction in the sense nearly half the actual value when gate is at 2.5 V or else :roll: Do specify

    AM transmitter antenna problem..

    Every Circuit uses DC power input to increase the power of AC signal Here the second ckt uses a 9V supply and considerable dissipation by the resistors is not of great impact and so The power of the second Transmitter Ckt is higher than the previous one which uses just a 6V DC margin for...

    AM transmitter antenna problem..

    True the power of this design is higher than your transmitter's design Bit range can't be altered drastically a little improvement is very much likely to happen

    Is energy regeneration is practical in electronic devices...???

    Be practical buddy How can you convert power lost in the inductor in the form of flux, lost in a battery It is not feasible
