Spectrum compensation for zero-order hold DAC [7 articles]

I just came across a concept that doesn't completely make sense to me, and I am hoping that the group can help me to understand more. I just received a copy of Rabiner & Gold "Theory of Applicati...

Enhancing resolution of an oversampled signal [20 articles]

Hi, I have an oversampled 1kHz sine signal with a sampling frequency of 62.5MHz and vertical resolution of 8bit. I take FFT (in matlab) to determine the signal's phase. What I need is phase accur...

multiplication of large numbers using convolution [16 articles]

Hi all, I figures out that the maximum number for which MATLAB can give an answer to factorial is 170. This triggered a thought in my mind I want to share with you guys. What if I take number in c...

Fractional Fourier Transform (FRFT) [3 articles]

Hi all, I am new on fractional fourier transform issue. A free matlab code on FRFT is available on internet but for inverse FRFT there is nothing. I have to implement inverse fourier transform. Ca...

help in filter coefficients [10 articles]

hi i'm doing my project in genetic algorithm.... i need to find the best filter coefficient value using this genetic algorithm..... i already designed one adaptive filter and also find its ...

Improve SNR via DSP [7 articles]

I am building an optical OOK (On off Key Ring) system without a carrier frequency. [However I have a guard time in between symbols, so a consecutive "1" messages will result in a pulse train as oppose...

Response to deterministic and random input present together [17 articles]

Hi, I am solving a mechanical vibration problem that has both deterministic and random signals simultaneously as an input. I would like to know if I can assume the deterministic signal as random si...

algorithms for star field compression [14 articles]

Dear all, I am working on the software of a Star Tracker device which should be capable to compress the images for transmission [1]. The CCD is 512x512 and each pixel is digitized with a 12bit ...

Maybe OT: Properties and description of surfaces that represent independent variables [9 articles]

I'm looking for some help here being able to describe the relationship among 3 variables. This is not homework. I wrote the question out the best way I can describe it. I'm the hardware guy w...
