The Numerix DSP Blog: June 2016
http://blog.numerix-dsp.com/2016_06_01_archive.html
The Numerix DSP Blog. All things DSP and some more . Friday, 3 June 2016. Frequency Domain Convolution And Filtering. Performing convolution and filtering in the frequency domain is a useful method of increasing the performance of these functions by using the fact that convolution in the time domain is equivalent to multiplication in the frequency domain. The down side is that there is increased end-to-end latency due to the requirement to translate between the time and frequency domains (and back again).

The Numerix DSP Blog: How to benchmark some C code (or assembly code, if you put the assembly in a C callable function)
http://blog.numerix-dsp.com/2013/01/how-to-benchmark-some-c-code-or.html
The Numerix DSP Blog. All things DSP and some more . Friday, 18 January 2013. How to benchmark some C code (or assembly code, if you put the assembly in a C callable function). I often have to benchmark DSP algorithms and while code profiling tools are excellent for large applications, DSP algorithms are often most easily benchmarked using simple timing functions. This first example uses the clock(). Long i = 0L, j = 0L;. T overhead, t start, t stop;. Calculate the timing overhead */. T start = clock ();.

The Numerix DSP Blog. All things DSP and some more . Thursday, 19 January 2017. Gnuplot/C On A Mac. I recently tried to install Gnuplot/C. I tried "sudo port install gnuplot wxwidgets" but ran into the DNS problem : https:/ trac.macports.org/wiki/MisbehavingServers. I doubt my ISP is going to change their ways at my request so I tried Brew instead :. Brew install gnuplot - with-wxmac. Perfect, lets test gnuplot :. Excellent, a nice little sinusoid. Now let's test Gnuplot/C :. Sudo mknod /dev/nul c 1 3.
