Select ONE of the following projects to discuss: a. Signal Filtering: You are given a sampled realtime waveform consisting of

57、a sensor reading mixed with highly periodic impulses and high frequency noi se.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 us ed. b. Interrupt Processing.A headware register consisting of eight

58、 independen t edge triggered latches is used to record external asynchronous interrupt req uests. When any of the request bits are latched, a software interrupt is gener ated. The software may read the latch to see which interrupt(s) occurred. Writ ing a one to any latch bit will clear the latch. Ho
