    Polar Capacitor as a Diode?

    Hi aniruddha, what are you up to man, when dealing with polarized caps always keep the polarity in mind and the maximum voltage rating also. ( if connected wrongly or the voltage exceeds the rating, the capacitor can burst and giving off quite a nasty smell). Electrolytic caps have a tendency to...

    How to transmit music from PC to music system wirelessly...??

    Hi chi_visor, where do you put up in INDIA? I also live in INDIA. i'm putting up in New Delhi. As audioguru suggested it would be better to buy a MP3 to radio transmitter. i got one for myself from Lajpat Rai Market for Rs450/-. it uses a single  AAA cell for the power supply and has a stereo...

    PAL007A datasheet

    Thanks for the help. one more query, the Pal007A is a 4X50W Mosfet IC while the TDA7560 is a 4x45W IC. i checked up the pioneer website, even they donot have a datasheet for the PAL007A listed there and in their parts section the PAL007A is replaced by the PAL007B. ;)

    Power supply for car amp

    You may try out an PC power supply. u can get one quite cheap these days and they provide about 25-30A at 12V depending on the wattage of the supply ( u can have a 400W supply for a home PC or a higher one used in servers) u may need to connect some load to the 5V output of the supply also as...

    Cutoff frequency and 3dB points

    Thanks for the replies guys but i'm still in the dilemma that why the 3dB spec only. Leaving aside filters, there is a cutoff freq for a device also (say a transistor). any body having any idea about transisent time concepts. i know these are the fundamentals but they are never thought in our...

    Cutoff frequency and 3dB points

    What is the logic behind the cutoff frequencies being defined at the 3dB points? why do we use the 3dB points only. is there some thing to do with transient time? these are some things we all study in our courses but what's the basis of these concepts. any one who can explain these basic...

    TDA1524A Tone Control IC

    The TDA1524A IC is a bit fussy when it comes to performance, i once tried making the circuit given in the datasheet. it worked fine with my HA1392 based amplifier but didnot work with my STK465 based amp. the bass corection network works great and the contour setting settinh really works. there...

    Need 2SA514 datasheet

    thanks for your idea but i don't think that it is an scr. i can't see a diac or so connected, all i see is a 7.2V battery connected through a trigger button ( which itself regulates the speed of the motor). the transistor is connected to the trigger button and the trigger button assembly also...

    IR Question

    generally all IR diode packages are made such that the field of emission is limited, a lens may help collimate the beam but won't improve the range much. to improve the range u'll need to use two IR diodes. ( as seen in some older TV remotes, it improved the range and also the field of emission...
