Hi, I have two questions.
1) See the picture 124236 124237
Here, in order to find **fundamental** **period** we divide the argument of the function by 2π. Like in (a)cos(0.01nπ) so the answer is f=0.01π/2π= then T=1/f=200.
But in (c) cos(3πn) the answer is T=2. Why?

The gong itself rings at a certain **fundamental** frequency, say 1 or 2 kHz. It has a clanging quality which is due to the presence of non-harmonic overtones (meaning they are not exact multiples of the **fundamental** frequency).
It is struck by the clapper many times per second, say 10 or 20 Hz.
I think you'll need to combine several sine waves, then

I read in a book that discrete time signals are **period**ic only if 'f' is a rational number. Why doesn't this rule apply for continuous time signals? For a continuous time signal x(t)=Acos(2πft) , let 'T' be **fundamental** **period**. Consider x(t+T) = Acos(2πf(t+T)) = Acos(2πft+2πfT)
By **period**ic property (...)

You need to ask yourself what Omega means. It is not simply the angular frequency in the sin / cos term. The overall function x is **period**ic, as implied by the N=19, so you can come up with the **fundamental** angular frequency corresponding to this **period**, and it is 2*pi/19.

The greatest-common-divisor of f1 and f2 is the **fundamental** frequency; the least-common-multiple is the **fundamental** **period**.
I think the first example is what you're looking for:

I'd use the cross() calculator function looking for the right-sense
zero crossings, and do the arithmetic to turn time into degrees.
Timebase being the **fundamental** **period** of whichever phase you
call the master reference.

Why does autocorrelation function approach zero at the **fundamental** **period** of a signal?

hi
Also I have the above problem.
Why there is not any newer version of "simulating switched-capacitor filters with spectreRF" document for spectreRF2008?
In the above doc the netlist defines only the **period** and maxacfreq; while in specreRF there are so more parameters required, for example "**fundamental** tones" and beat frequency simultaneusly. A

As you could see in
Illustrating the sine wave's **fundamental** relationship to the circle.
on wikipedia...
Its actually a plotting over the circle
consider r=sinΘ
now for all different values of Θ you will get different values of r..
now if you had to plot r versus Θ.. then one convenient way is to plot values of r (as

Hi guys, i just recently succeeded with functioning stepper motor with PIC and UCN5804B, so i just did a **fundamental** test on stepper motor by pumping in different speed in the coding, but with 50% duty cycle. So i tried with 16ms **period** until 1.5 ms **period**, so 16 ms makes the motor slow and 1.5 ms makes it fast. i
understand how

Hi friend,
i replyed your message on the group and i will rewrite it here again;
Regarding your qestion which was the **fundamental** **period** of cos(pi . n^2/8), I see if wee add N to n as followes:
pi/8^2 = pi/8 (n^2+2nN+N^2)
pi/8^2= pi n^2/8 + pi 2 n N/8 + pi N^2/8
now according to your result that is the minimum **fundamental** p

Your ECG signal has very low amplitude at the **fundamental** frequency, so a plain FFT would give you poor info.
It would be better to apply some sort of non-linear filter to it first, such as computing fft(ECG_1 > 0.5) instead of fft(ECG_1).
This example shows the first strong spectral peak at about 1.23 Hz. Zoom in to see it:

Ok, I located the example problem. Frankly, I dont understand your question. Are you speaking about Figure 3.7?
The figure explains the effect of different **fundamental** **period** T of the rectangular pulse. If T = 4T1, meaning, the rectangle pulse lying in the origin extents from -2T1 to 2T1 and if T = 8T1, then same lies between -4T1 to 4T1.

Note that
For a discrete-time signal to be **period**ic it has to satisfy
x=x where N is the **fundamental** **period** and the condition on it is that it should be an integer.
For a continuous-time signal to be **period**ic it has to satify
x(t+T)=x(t) where T is the **fundamental** **period** and there is no r

Hi all,
i am new to Matlab.Could anyone help me to generate and plot the below 3 sequences using Matlab "stem" function
qn1) What should i define in my script?
qn2) how do i obtain the **fundamental** **period** by just observing the graph?
x1=sin(0.6Пn+0.6П)
x2=sin(0.68Пn)
x3=3sin(1.3Пn)-4cos(0.3Пn+0
