Fir filter 2 (3 zeros) b[0] = b[1] = b[2] = b[3] = include the pole zero plot and magnitude bode plot in your lab reportwhat type of filter is this? (lowpass, highpass or bandpass? ) checkpoint 4: clean up and show your workbench to the lab monitor. discussion questions: topic 1: draw a block diagram of the physical lab set-up for procedure 2. label connections with the name of the signal that they carry. include the device playing the. wav file, speaker, etc. divide the c2000 kit into codec and mcu. topic 2: draw another block diagram of the functional lab set-up for procedure 2. this system includes all of the processing blocks, signals, and data such as. wav file, d/a on your mp3 player, analog signal, the a/d in the codec, the d/a in the codec, etc. label arrows between functional blocks with the name of the signal that they carry. indicate your fir filter. topic 3: draw a flowchart of the main routine and the interrupt service routine for the fir filter program. combine code into functional blocks, e. g. "initialize codec ", "interrupt mapping", note that an infinite loop looks like this in a flow chart: in the main routine, wd is the watchdog timer, which must be written to periodically to prevent the mcu from automatically resetting.
