It also makes it possible to detect and measure faster pulses and signal edge speeds. More bandwidth means less signal attenuation at higher frequencies. Oliver Rovini, Chief Technical Officer, said “At 4.7 GHz, these new digitizer cards offer our highest bandwidth capability to date. These include Window, Re-Arm, Delay and Software triggers, as well as the ability to use the cards inputs (channel, trigger and digital lines) to set up specific trigger conditions based on Boolean logic. Conventional edge triggering, which includes trigger time stamping, is enhanced by a number of sophisticated trigger modes that help with the capture of the most elusive events. Multiple-waveform recording allows the capture of numerous events, even at very high trigger rates. In fact, if I was trying to use my straightline function with some other code that required lines to be defined by slope and intercept first, and then the abscissa, I can easily create a new interface for the line.Acquisitions can be made in both single-shot or multiple-waveform recording modes. I could also use it to create a function of just slope and intercept, suitable for create line segments for different parameters at a later time. In the first case, I turned my function of 3 variables into a function of one variable, with preset parameters. Using the same original function definition for straightline, I am able to mold the function for different purposes. Newline2 = straightline(X, slp(2), intcpt(2)) Īnonymous Functions Allow Interface Flexibility Newline1 = straightline(X, slp(1), intcpt(1)) I can even get the values put into a slopeIntercept = straightline(data, slope, intercept) In that case, with data supplied, I can derive such a function from straightline. Perhaps I instead want a function of the slope and intercept only. Now compare estimates for slope and intercept to original values. ![]() Now I want slope and intercept to be my independent variables. ![]() m = 2 ĭata = straightline(t,m,b) + 0.2*randn(size(t)) And we would like to estimate the slope and intercept values. Now suppose we have data, based on this line segment, that has some noise. myarea = integral(myline, lowerlimit, upperlimit) Use this new function, myline, as the integrand. lowerlimit = 2 Ĭreate a function representing my particular line segment, by fixing those slope and intercept values, and creating a new function from the original one. Since the function integral requires the integrand to be a function of one variable only, we can use the anonymous function myline, defined below, to create just such a representation. Now let's find the area under a segment of this line, between two points. Now I can evaluate my function when I create the plot. I start by defining the slope and intercept values. straightline = slope*X + interceptįirst let's choose a particular straight line segment. Here's a very general way I can write the code meant to generate points on a straight line. ![]()
