    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

    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

    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

    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...
