can anybody help me to implement the following transfer function as an
biquad circuit.
H(s) = 1.77*10^5*s + 1.58*10^10
---------------------------
s^2
thanks in advance.

please someone respond to my problem.the transfer function to be implemented is H(s) = (1.77*10^5*s + 1.58*10^10)/s^2>can anybody help me to implement the following transfer function as an >biquad circuit. > > H(s) = 1.77*10^5*s + 1.58*10^10 > --------------------------- > s^2 > > >thanks in advance. > >

If I understand your question, you were given an assignemnt of taking a particular transfer function and implementing it as an analog circuit and you are running out of time and have little idea of how to begin. You need to review the transfer function forms of the filters and circuits you have been studying and you will probably find one that matches. Once you identify the form, you should be able to use the coeffecients to calculate component values. If you aren't finding any forms that match exaclty, notice that some of your terms are 0, such as the first and zero order term in your denominator. sid4u wrote:> please someone respond to my problem.the transfer function to be > implemented is > > H(s) = (1.77*10^5*s + 1.58*10^10)/s^2 > > > > > > >can anybody help me to implement the following transfer function as an > >biquad circuit. > > > > H(s) = 1.77*10^5*s + 1.58*10^10 > > --------------------------- > > s^2 > > > > > >thanks in advance. > > > >

I wish I had access to a resource like this when I was in school. I could have gotten straight A's and not even had to learn a thing.

The engineering school had just under a tenth of the students (all undergraduate), and electrical engineering accounted for half of it. Two graduations were held each year, one at the end of the fall semester that included people who earned their diplomas over the summer, and a slightly larger one in June. I graduated in June in a class of exactly 400 EEs and 800 engineers overall. (Despite having flunked out in an earlier attempt, I was the bottom member of the top tenth of both groups.) A school like that is too big to foster much interpersonal competition for grades. The better students held regular tutoring classes for anyone who needed help, usually under the auspices of the various honor societies. I don't know if the tutors or tutees benefited more. I do know that many people were saved from dropping out of the curriculum. Sometimes, there's a hump to get over; something has to "click", and then suddenly a subject comes clear. We tried and often succeeded to pull and push our fellows over that hump. We didn't do homework in general, but sometimes we did our own homework jointly with our slower classmates. That's different from saying, "Here. Just copy mine." One of the most surprising aspects of City College given it's enormous size was how personal our relations with the faculty were. On my first day back for my second try, the dean of the liberal arts school stopped me in the hall, addressed me by name, and asked what I was doing there. He has been my calculus professor a few years before.

I had a group of friends that and we used to arrange to be in the same classes. We used to gather, mostly at my house since I lived right off campus, and go over the material, study for tests, etc. We didn't however, outright copy the homework. I do remember one time, though, that there was a student in a class who was about to fail the class for the 3rd time. It was a required class for the degree, not an elective so there was no way around it. You were allowed to take a class three times, but that was it. The teacher was refusing to "just pass" them and the dept dean was standing behind the instructor. I remember talking to the instructor about it. He said that to "just pass" them as other teacher had been doing would only serve to belittle everyone elses work. He said that what would happen is that this person would get out in the work force, be unable to perform their duties and then everyone else who had the same degree from this institution would be viewed as having the same poor qualifications. The O.P. asking for answers like that is in the same boat, but the idiot who "gave" them the answer is like the teachers who would just pass the failing student to get rid of them.

I goes all the way down to grade school. I'm working with 14 yro who would be classified as "at risk" even if he weren't ADHD with additional learning problems. He received 'social promotions' all the way into 7th grade wo being competent to add/subtract fractions and lousy reading skills. Fortunately the middle school he was dumped on sees the problem - I give him a 40-60 chance of promotion. The kid is *NOT* dumb. While working with him on one problem regarding fractions, I slipped into using algebra in my explanation. He 'got it' immediately even though he had never had any algebra. Currently I'm working on reading skills using _The Lion, the Witch, and the Wardrobe_ by C.S. Lewis. Now just how much language commonality is there between a 21st century Ozark Mountains teen and an early 20th century professor of literature at Oxford and Cambridge? He regularly asks me "why didn't he say 'abc' instead of 'xyz'? He's been fascinated by the limited insight into linguistics that I've been able to give him. kid *NOT* dumb was *NOT* served by undeserved promotions And now there are ~!@#%$#@% teacher unions objecting to bonuses for teachers who actually teach. AGGRRRHHHH temp end of rant :)
