    [SOLVED] Matlab Code to read WLAN (Wifi) Signal strength

    Hello, I want to read & plot wifi signal in PC. Can we read Signal strength of Wifi (WLAN IEEE 802.11) in matlab? If not, what are the other methods to read and plot my PC wifi signals? If you have sample code or useful links please share with me. Thank you, Regards, Naveed

    long distance serial communication

    Hi Waqas, There is a distance limitation for Rs232 standard, this distance depends on data-rate(baudrate). You can send and receive data through MAX232 for 30 feets (9.14 meters) if you keep your baudrate 9600 bps. Refer to the given link for baudrate and distance details. Lengths of serial...

    Partial Product Multiplication in (Hardware Multiplier/MACs)

    Hi All, Anyone know about the advantages of Partial Product Multiplication over normal Multiplication?? I have seen some latest publications in which they use "Partial Product" in hardware MAC/Multiplier unit. Thanks & Regards, Naveed

    Want to control 220v AC

    Its not necessary to use MOC3041 , you can also use MOC3021 or any other which is available/compatible. The part number for triac is BTA16(if you want to drive 16A AC load) , it depends on your load.

    Multiply and Accumulate Architectures for FIR and IIR filters

    Thanks for the reply chitturi, Can you give the name/number of the processor which you are referring to (10 point FIR in 1 cycle , 10 point IIR in 3-4 cycles). If you have some documents on survey on it , can you provide the documents too? Thanks & Regards, Naveed

    Want to control 220v AC

    You can use BTA16 triac with an optocoupler. Your microcontroller will trigger the optocoupler which will trigger the triac. BTA16 can pass 16A current, which is sufficient for your load. This is how you can Isolate AC and DC. Naveed

    [SOLVED] ARM1176 (VFP) Vector Floating Point Push/Pop

    Hi, I am using ARM1176 with VFP(Vector Floating Point Co-processor on chip) on Linux, I want to push single precision registers on to the stack. When I push them on to stack, compiler complains and says "ARM register expected" . Can we push S1,S2,S3 on to stack? I dont want to go with other...

    Force variation with increasing/decreasing distance and angle?

    What do you mean by lower side supported? I mean we only have two sensor points that are UL and UR. At the lower side there are no sensors mounted!

    Extracting data from GPS Cell phones

    If you are planning to use external Microcontroller then it is much easier. What you can do is, you can find some test points for GPS and GSM modem which are built-in in your cell. 1. I hope GPS will have UART interface you can take out those pins externally and connect it with your...
