Circuit:Low pass and High Pass
The nature of lake is that there is a giant explosion of whatare called “midges†in the mid to late summer. If you haven’t beenaround and seen these bugs:
Your car gets covered so bad that you can’t see out thewindsheild after driving 10 miles! They get everywhere; don’t openyour door at night as they flood in! Now althought this is seen asa menace from bug hell, there are some not so obvious advantageswhich come from this menace. Who see the bugs, catch them and feedthem to their young. And Who “see†bugs through sonar,their voicesare their “eyes and earsâ€.
Professor from the Environmental program is trying to get anestimate of the population of bats that are around the lake toquantify the relationship and population dynamics of bats to theseverity of the menace. Now bats are night creatures you see, wellhe can’t see so well as it is night! He is at a conundrum for howto measure the number of bats in a given area. Very difficult to doas you can’t visually (unless you have a light, yet this willprobably throw off the count of bats as the bugs are attracted tothe light, hence bats also, yet this would lead to an unnatural ornot normal distribution of bats!) so he must be away from thestreet lights further down the road and the lights from cars withthat blasting stereo to drowned out the new street performancemuffler shouldn’t affect the natural distribution of bats. Thesecond issue is that bats don’t fly in formation, they come fromall directions almost randomly. Prof. has come to you for asolution to his bat count problem. Using the knowledge you havegained, come up with a simple design to help Prof. count his bats.Describe your solution and reasons why you chose this solution.Include any calculations and a concluding paragraph of what youhave learned in this problem.
