Determine the coefficients of a linear-phase FIR filter of length M = 21 which has a symmetric unit sample response and a frequency response that satisfies the condition Hd 2πk 21 ! = ( 1, k = 0, 1, 2, 3, 4, 5 0, k = 6, 7, 8, 9, 10 Generate a plot of the frequency response magnitude over ω ∈ [0, π].

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
