Memory utilization for FIR filter implementation.Each filter is implemented in a fixed-point format3-5 in which each data contains 15 bits formagnitude and 1 bit for sign bit (Q-15 format). The 2’s complement form is used for any Page 22.1384.6negative number. The designed FIR filter coefficients are quantized into 16 bits as following: b0 0.006 215 197 , b1 0.0493 215 1615

pressure and Blower Door fan flow readings. It's specialized "Baseline" and"CFM @50" features makes it extremely easy to get quick and accurate airtightness test results. Using adoor screen, a variable speed blower was used to change the airflow through the envelope and theelectronic monometer (DG-700) was used to record the pressure differentials and air-flow rates betweenthe room and the hallway.Air infiltration can be calculated using the power law equation where Q is the airflow rate, C is the flowcoefficient, ΔP is the pressure differential and n the power coefficient. Q  C.P nThis equation shows how much air is leaked to the outside surrounding and how air infiltration varieswith respect to a
