WebMar 3, 2010 · Let's sample with a sampling frequency of 800 Hz. T = 1/800; nmin = ceil (tmin / T); nmax = floor (tmax / T); n = nmin:nmax; x1 = cos (2*pi*f * n*T); hold on plot (n*T,x1, '.' ) hold off The sampling frequency of 800 Hz is well above 120 Hz, which is twice the frequency of the cosine. WebFeb 13, 2024 · You say your sampling rate is 100 Hz and the signal is 10 Hz. Lets define those along with the sampling period ( 1 / 100 seconds). sampleRate = 100; samplePeriod …
How to know sampling frequency of a sin(x) function
WebThere are several types of functions used in MATLAB. They are as follows: 1. Anonymous Function It is the function that is not stored in a program file, but it is associated with the variable whose data type is function_handle. It is defined in a single statement and has any number of input or output arguments. The syntax can be written as: WebUse the sawtooth and square functions in MATLAB to generate the two sequences shown and plot them using stem . I input data specified by the user are are the length of the sequence (L), the peak value (A), and the period (N). Use A=8, L=30, N=11, and Fs=10kHz. 4. Aliasing On one graph plot three sinusoids with frequencies of 3 Hz, 7 Hz and 13 Hz. holiday inn express wabash

WebSampling a large data set preserves trends in the data without requiring the use of all the data points. If the sample is small enough to fit in memory, then you can apply plotting … WebMar 26, 2014 · The matlab imresize function provides a number of ways to perform interpolations. It's possible to test the error resulting from a downsample/upsample operation for a particular kernel: I = int8 (imread ('rice.png')); J = imresize (imresize (I,0.5,'box'),2,'box'); mean (abs (J (:) - I (:))) Running this code with different kernel types … http://www.ee.nmt.edu/~rison/ee451_fall96/matlab/sample.html holiday inn express wabash ave chicago
