novicelabview

Hi all, I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be around 120 hz and 150 hz . I am using USB - 6003 daq card. I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase same as the input signal. I have seen a PLL vi , but dont know how to use that with my program. can any one tell me how to proceed. thanks

Hi All, I am new to image processing, and wondering if there is a way to create 3d image array which contains at least 5 frames of the image data from the grab vi? I want to do temporal median filtering using labview is there a way to do that. I need to take the median of the pixels of each of those frames and create one median array and then convert it back to image. can any one please help me out in this. thanks

Hi all, I am trying to do some image processing , I want to make an application which will do median filtering and spatial filtering with continous acquisition of images from a gige vision camera. I tried to use nth order vi but I couldnt understand whats the filter x and y should be . images from camera are Mono 8 with height and widht set to 1000. how should i configure the median and spatial filter to do this processing continously with acquisation. I want to have atleast 5-6 frame persec for my filter. attached is my try with median filter if I change my filter size (x-y) to more then 10 , my labview crashes. Please tell me how can I configure the median and spatial filter for this image processing application. Image median.vi
