    Hi Friends,

     
    I have written the exam of AAI for JE(Electronic). The paper consists of general aptitude, GK, and techincal questions. Some the questions, i got in my paper are.
     
    1) Hall effect is used to measure?
    2) A question on network?
    3) ROM is  non volatile storage device?
    4) RAM is not used for long storage puprose because. When power is lost we loose the memory?
    5) Non programmable device is 8212?
    6) 7400 is Quad NAND gate?
    7) NMOS cutooff voltage?
    8) Yagi uda antenna radiation pattern is?
    9) Helical antenna is used in satellite becoz in RC phaseshift oscillator a condition to get oscillations in hfe>= 4K+23+29/K. If there are 8 sections in RC phase shift oscillator then each section has a phase shift of 45degrees directivity of half wave dipole is 1.64?
    10) Voltage series has  input impedance is high and output impedance is low?
    11) READY signal is used in MP because of slow devices connected?
    12) TRAP is non maskable interrupt?
    13) There are several 1K byte memory devices to be connected to memory chips and address lines connected to be are AD0--AD9.
    14) When on write signal if a pulse is from low to high then the address/data bus lines contains.
    15) RAM serves the function of
