The largest blackout in US history occurred on August 14, 2003. It affected eight US states and parts of eastern Canada. Millions of people were without power, some for multiple days. After a long investigation, the cause was determined and actions were set forth.
Read the report by the NERC titled "Technical Analysis of the August 14, 2003, Blackout: What Happened, Why, and What Did We Learn?" Write a 500 - 550 word essay on the blackout, what caused the blackout, and any governmental regulations that were a result of the blackout and report. Reference at least one source in addition to the report, and format according to APA standards, 6th edition, including title and reference pages.
A negative feedback amplifier has a close-loop gain Af=100 and an open-loop gain A=105. What is the feedback factor If a manufacturing error results in a reduction of A to 103, what close-loop gain results
What is the primary purpose of a window function? For a 7-term moving average filter, what effect do the poles have on the frequency magnitude response and why?
