1. Select ONE of the following projects to discuss:
a. Signal Filtering: You are given a sampled realtime waveform consisting of a sensor reading mixed with highly periodic impulses and high frequency noise.The desired output is the realtime filtered sensor signal with the impulses and noise removed, and a readout of the impulse period. The FFT may not be used.
b. Interrupt Processing.A headware register consisting of eight independent edge triggered latches is used to record external asynchronous interrupt requests. When any of the request bits are latched, a software interrupt is generated. The software may read the latch to see which interrupt(s) occurred. Writing a one to any latch bit will clear the latch. How does that software assure that no in
