of an integer number of clock cycles of the frequency signal within a respective gate signal period of the gate signal; a second measurement circuit having a time-to-digital converter (TDC), where the TDC is controlled by the gate signal, and is configured to generate a second estimate of ...

However, this global encoding method resulted in a full spatial correlation of the modulation structure imparted on the signal, which limited the compression ratio and hence sequence depth. Thus, ultrafast encoding over each pixel is beneficial from the standpoint of improving reconstruction fidelity34...
The digital oscilloscope used to record the traces introduces a low level of noise spanning the complete bandwidth of our detection system (out to 40 GHz) with a constant level and, to improve signal fidelity, we apply a frequency-domain numerical filter which allows us to more clearly ...
Everybody good, my name am Chen Mingchao.My nickname is “chirp chirp”.I am an extroverted boy.I biggest shortcoming is the speech too are many.I graduate from the wanning middle school.I very happy can in here and everybody understanding.Now, you are willing to make me this friend?
Rice's formula^1for the "envelope" of a given signal is very cumbersome; in any case where the signal is not a single sine wave, the analytical use and explicit calculation of the envelope is practically prohibitive. A different formula for the envelope is given herein which is much simpler...
antenna, transmits to a fixed RTLS sensor with a multi-antenna array. The phase shift of the multiple antennas, as a result of receiving the signal, is measured and calculated to determine the angle of the transmitting mobile device and create an area of certainty of the object to be ...
1.- note that the 101 applied on the input signal here, so both signals can be compared, so it's the output that has to be attenuated by length(x) to get back to the signal level. 2.- MATLAB already warns: Warning: Imaginary parts of complex X and/or Y arguments ignored So, bas...
For ease of understanding, we assume the instantaneous frequency of the IF-LFM signal is f IF(t) = f 0 + kt, where f 0 is the initial frequency and k is the linear chirp rate. The DPMZM consists of two sub-MZMs (MZM-a and MZM-b), and each sub-MZM is embedded in ...
Think of stationary noise as something with a repeatable yet different pattern than human voice. Traditional DSP algorithms (adaptive filters) can be quite effective when filtering such noises. Non-stationary noises have complicated patterns difficult to differentiate from the human voice. The signal ma...
