In situations like Fire accidents and Gas leakage emergencies, quick conveyance of information is needed, quick conveyance of information of information methodologies adopted in advanced nations. But for a developing country like India, a replica of such systems may not be feasible due to the cost factor. Hence an effective and economical alternative is necessary. Integrated Emergency Response System using GSM (Global System for Mobile communication) system provides a cost-effective automation for automating Fire Alarm System, Gas leakage detec..............etc

Procedure:-
1. Rewrite the difference equation so that y and its delayed samples are on the LHS
2. Create a matrix a for the coefficients of y and its delayed versions
3. Create a matrix b for the coefficients of x and its delayed versions
4. Generate impulse excitation signal delta
5. Find the response h of the filter defined by a & b coefficients , so the input impulse excitation , using filter command
6. Display the impulse response h.

Air brakes are used in commercial vehicles, which require a heavier braking effort than that can be applied by the driverâ„¢s foot. The following layout shows the arrangement of the air braking systems in heavy vehicles.Compressed air from compressor passes through the unloader valve and maintains its pressure. This air is stored in the reservoir. From the reservoir it goes to the Brake Chambers through many brake valves. In the brake chamber this pneumatic force is converted into the mechanical force and then it is converted into the rotat..............etc

DESIGNING A FIR FILTER:
Following are the steps to design linear phase FIR filters Using Windowing Method.

I. Clearly specify the filter specifications.
Eg: Order = 30;
Sampling Rate = 8000 samples/sec
Cut off Freq. = 400 Hz.

II. Compute the cut-off frequency Wc
Eg: Wc = 2*pie* fc / Fs
= 2*pie* 400/8000
= 0.1*pie

III. Compute the desired Impulse Response h d (n) using particular Window
Eg: b_rect1=fir1 (order, Wc , 'high',boxcar(31));

IV. Convolve input sequence with truncate..............etc
