The frequency response represented by Bode's Diagrams is only valid for linear systems. Non-linearity means that the gain and **phase** introduced by your system depends not only of the input frequency but also of other parameters (input signal's amplitude, input signal's bias, input signal's frequency).
Thus, in order to represent the frequency respo

Sounds annoying but sometimes a higher frequency oscillator could have lower **phase** noise than a lower frequency oscillator, even they use the same active component.
Leeson **equation** stated that: doubling the operating frequency the **phase** noise increase by 6dB, but in the same time, doubling the loaded-Q of (...)

hi antenna experts.
i designed a Reflectarray unit cell with proper **phase** shift in CST.
i used unit cells in array and fed it by a horn antenna.
the solution type is integral **equation**.
now i want to know how can i gain the **phase** of each element(**phase** of fields or (...)

Hello All,
I had a question regarding the **phase** relation between the RF input and IF output of a down converting mixer. I am attempting to make a device which can measure the **phase** or delay of a particular DUT at X-band. I attached a simplified block diagram of the circuit below.

Hi, all.
I am simulating a VCO after an ideal bandpass filter. The **phase** noise of original VCO is about -122 dBc/Hz at 3 GHz.
Then I set bandpass filter by using cadence functional block, Q=50, at 3 GHz. However, the **phase** noise after filtering
is only -75 dBc/Hz.
I am not very sure where I did wrong.
Hope (...)

Hell, I'm having a problem working out a few questions....
v = 120 sin (50πt + 1.1) V
I need to work out frequency, amplitude, relative **phase**, value of v when t is 20ms, if this voltage is applied to a resistance of 100ohms what would be the **equation** for the instantaneous current?
I think the frequency is 50 and the amplitude (...)

Hi,
In Phillips' paper: am quite baffled by his comment "impulse response of the **phase** deviation phi(t) can be approximated with a unit step s(t)". Why and how to explain that?
Further, how to derive **equation** (6) from

The impedance of a capacitor is inversely proportional to frequency as shown by the **equation** you referenced.
...and we shouldn`t overlook the fact that the term "impedance" involves also a **phase** shift. This is an important property that is exploited in many circuits (example: integrating circuits).

The **equation** for this filter according to this book "Simulation of Communication Systems" by Kluwer is defined as
H(f)=exp(j*\theta*\omega^2)
where \omega=2*pi*f and \theta is "the **phase** at a reference frequency of \omega=1rad/s".
What does "the **phase** at a reference frequency of \omeg

Hi,
For the first order loop, its difference **equation**s are easily got. But for the second order loop BB PLL, it looks like unclear to get the difference **equation**s. More specifically, I am not clear about the VCO output **phase** term at the BB PD input, see equ. (4) below please.

Dear friends,
I need help in choosing RFID development board or RF TX/RX evaluation board. The goal is to find the **phase** of the received signal by using the I and Q information after demodulating the received signal. The **equation** to calculate the **phase** is arctan(Q/I). I don't care about how what the data (...)

The FFT decomposes the signal in frequency, generating a complex spectrum with both positive and negative frequencies, depending on both amplitude and **phase** relationships. We are now not interested in the **phase**.
Fixing a frequency, the absolute amplitude for positive frequency is the same of that in the negative part. So, (...)

I created a BPSK signal in Matlab and I'm wanting to extract the unwrapped **phase** from the instantaneous **phase** obtained. The detail is that the result will apply an **equation** to get the centered non-linear component of the instantaneous **phase** which is given for "phi_NL" in the (...)

Hi guys,
I am a student currently working on a project to design a **phase** locked loop and I have a problem with designing the loop filter, which is a passive lag like in most textbooks. Basicly I am designing and building a PLL for a pretty specific scenario where noise performance is the upmost concern. My question is this:

Can anyone explain how to get the dispersion diagram(**phase** constant) using HFSS simulating the metamaterial antennas(for example leaky wave antenna)
For metamaterials, it is possible to get the dispersion diagram by this way:
Simulate the HFSS model, and get the S pameters
Then program in the matlab using the S parameters.
