    Intell 8085 microprocessor and the control and timing unit

    I have been studying the Intel 8085 microprocessor and studying the machine cycle and bus timing diagrams. I have noticed one thing and want your confirmation. I feel that the control and timing unit is crucial to the working of the Intel 8085 microprocessor since it generates the necessary...

    PWM and music playback

    I have the .wav samples (unsigned 8-bit PCM) of a music file that I want to play using the AVR microcontroller. I have enough flash to store these samples and would like to know if it would be easier to play it directly from the flash or should I store them on the RAM and then play the samples...

    Time Scaling of Signals

    Thanks for your answer ahmad1954!!! I didn't quite understand what you meant by "if we want calculate two function in 1"...what i did understand is that in the transformed graph the time axis is 1/a times (say t') the original graph's time axis (say t)...but how does the transformed graph become...

    Time Scaling of Signals

    I have a very basic question to ask! I have just started a course on signals and systems and I am finding time shifting and time scaling very confusing. I don't understand how by multiplying by a factor >1 the original signal gets compressed i.e. why is x(4t) is a compressed version of x(t)...

    Minimum System for AVR microcontroller

    the avr is a microcontroller, right? What I am trying to say is that don't we have something to connect first to the microcontroller before we can program it? Just as in the 8051 we have a DIP but u can't program with the DIP right away we need some sort of Trainer like the one right here...

    Minimum System for AVR microcontroller

    I am completely new in the field of microcontrollers and now I have to start making a project! I have selected a microcontroller from the atmel atmega series but since the pin configs. vary from each microcontroller, I am confused as to how to develop a minimum system. Also if I order a...

    Applications Of Quadcopter

    Hey please can anyone give me a project idea using the quadcopter that might be useful as an application in itself? I thought about following/chasing but anymore?

    Junction of SCR (J2) and junction of Diode

    After you remove the gate signal only the +ve anode w.r.t cathode remains hence electrons are flowing one way and holes are flowing the other way, now if that is the case then current must necessarily flow in common emitter mode of a transistor with collector-emitter voltage applied and...

    Junction of SCR (J2) and junction of Diode

    I want to know why SCR conducts even though the gate signal is turned off. It sounds like you don't know anything about electronics yourself otherwise you would have given me an answer explaining me the exact operation of an SCR rather than quoting me in your answer...How does the regeneration...

    Junction of SCR (J2) and junction of Diode

    1.) When the SCR is in the forward conduction mode and positive gate signal is applied to the p region of junction j2 then why is it that after a threshhold value is reached the gate signal can be switched off? 2.) Won't the J2 become reverse biased again? 3.) In a transistor (BJT) a constant...

    Examples of capacitors and inductors...

    can you give an example as to where capacitors and inductors are used? i know capacitor's store energy between their plates and inductors store energy in the magnetic field surrounding them and also capacitor is like a 'resistance' when the source voltage is fluctuating and also the inductor is...

    Capacitors and Inductors...

    I don't know when to use a capacitor and an inductor in a circuit? I do know that capacitor impedes any change in voltage and inductor impedes any change in current. Using this information I am again confused because in a capacitor if there is a voltage spike in the power supply the energy is...

    [SOLVED] HELP....BASICS OF TRANSISTORS(Any help will be appreciated!)

    I understood the transistor action(emitter-base voltage acts like a gate and allows more electrons to diffuse into the collector region and the voltage applied to collector acts like a suction to **** all the electrons) but now when we have different configurations such as "Common" Emitter and...
