    Undergrad Modelling Long Sets of Data: Measuring "Harshness

    well the other [quite odd] thing about this is that i was thinking of mostly working with square waves... that's why 1s and 0s anyway. but i think i changed my mind and want to work with spectrums. again it'll be a lot of data tho... maybe less than 500,000 cells but now it's not 1s or 0s...

    How can I create a dataset with a specific curve and add noise to it?

    i was trying to run ifft on excel but i then want to manipulate the output [basically - everything above the median amp = 1, everything below = -1. turning into steps]... but this destroys the fft - completely. is there no way around that - i was thinking of using solver and ifft in excel...

    no help - not even anything i can google? sorry - i keep changing what iwant to be doing haha :)

    Undergrad Modelling Long Sets of Data: Measuring "Harshness

    say i have 500,000 0s or 1s. say i have 50 such sets, each that i have ranked or assigned a value to - "harshness". can i then extrapolate - is that the right word - to find the perfect dataset that instantiates the property of harshness? and can i measure the harshness of other datasets...

    High School Can I Solve for A and B in These Equations?

    thanks - I'm trying to find it with excel atm. not sure if these figures even converge tbh.

    High School Can I Solve for A and B in These Equations?

    they don't converge! what about: 100=A/(100-B)+C 12000=A/(80-B)+C 200=A(5000-B)+C thanks!

    High School Can I Solve for A and B in These Equations?

    honestly - i am using software that runs out in like 20 hours. this is a music hobby thing - i don't suppose you can give me the answer plus also if excell will do it for me?? i know it'd be simple for everyone here... :) :) !there are online calculators but they don't seem to cope with the A*B...

    High School Can I Solve for A and B in These Equations?

    also is there any way to set up excel so that as i change the figures the answer what A and B is automatically changes? i'm sorry to be so bad at math - it's been like 12 years since i stuided any :o

    High School Can I Solve for A and B in These Equations?

    80A = 12000 - AB 2000A = 2000 - AB I can find A and B right? If not I can provide more?? Thanks :o !

    How can I create a dataset with a specific curve and add noise to it?

    oh i can create data approaching the trend... i don't know how to do so efficiently yet tho ha.

    How can I create a dataset with a specific curve and add noise to it?

    yup. i started a new thread now in analysis section if you want to help :)Luke

    Undergrad Meauring deviation of something using some party randomized variables

    hi, i want to take an x-y data set and find the deviation from another dataset. the master dataset is two identical y=1/x curves of different amplitude; also one only registers at periodic intervals and the second is multiplied by a noise signal. so part of the problem is going to be...

    How can I create a dataset with a specific curve and add noise to it?

    see the follwing print out - you can imagine what the trend might be - the dataset i want to make?? how can i create that data. i mean that sort of curve twice - the second time of a lower volume with noise added. make sense?http://imageshack.us/f/703/40382180.png sorry for some reason i can't...
