This is my first question so I'm not sure if it is the right category. Otherwise I would be glad if moderators can move this to a more roper category if there is.
A single-ended -10V to +10V 16-bit data acquisition system is composed of 16 single-ended channels where two of the channels are analog outputs and th

Dithering and oversampling help to "see" **signals** whose level is below one quantization step.
Dithering, by giving to the quantization noise (that is non**random** for very low level **signals**) statistical properties like **random** noise.
Oversampling, by distributing the noise power over a wide bandwidth (wider than the band of (...)

Why is it necessary?
So your analog logic doesn't start doing some **random** function, and in the reverse direction, so help improve test coverage.

Hi all,
I am trying to give valid test patterns (As in give a test pattern that ensures that none of the **signals** are unknowns). I tried giving **random** inputs every cycle, I decreased the clock frequency. But still I am getting undefined values after a large number of clock cycles. Please advice me on how I should proceed?.
Regards,
Prabanja

Is there any way out to separate ac and dc **signals** ? I mean if input is a **random** signal containing both ac and dc parts , then is it possible to separate ac and dc ? Will capacitor be of any help because a capacitor blocks dc ?

Hello all,
I have a large RC network that I am simulating in HSPICE (on Linux). The voltage sources are all DC and the current sources are **random** PWL **signals**. I am trying to figure out the number of system solves that HSPICE is performing to finish the simulation. In the output generated on the terminal, there are two entires: "tot. iter" and "c

Are you sure the TIG actually is in effect? Those pesky constraints have way of letting you think you have applied them, but in actual fact they do as they please. I'd double check that the constraints are actually applied. Notably, make sure you apply the constraints to the flip-flops (registers), NOT some **random** wires aka **signals**. Been the

A "conceptually"-deterministic signal might be a signal that is defined by an exact equation (e.g. sin(t), for all real numbers t), which has no **random**/stochastic/probabilistic component.
IF I am using the correct definition of "deterministic" (i.e. "not stochastic"), then I believe that all "real world" **signals** would not be deterministic, and w

Hi,
I am trying to assign **random** values to the inputs of my design. I would like to do in the TCL scripts. I have the TCL for the Modelsim. I need something similar in the NCSim.

# Find all the inputs and add them to the set

Hello all,
I want to determine the power level (dB amp) of (supposed to be wgn) **random** signal using oscilloscope data. I have compiled a code to do the job but when tried to verify my code for several different **signals** (periodic sinus, **random** gaussian) generated on MATLAB, I have seen that the code yields different power levels for (...)

Hi Everyone. I am implementing a Kalman filter for an accelerometer. As you know,the accelerometer can be modeled as a **random** Walk process and the output of a **random** walk process is assumed to be coming out of an integrator driven by white noise. This is described in "**random** **signals** and applied kalman filtering, (...)

What exactly are you expecting to see?
If you use an untuned amplifier the output will be a combination of possibly thousands of **signals**, all with **random** amplitude, frequency and phase. The result will look like **random** noise unless one of the **signals** is much stronger than the rest, in which case it might be distinguishable (...)

A **random** signal from a deep-space probe is uniformly distributed between 17.324V and 32.574V.
It is observed in the presence of Gaussian noise N having zero mean and standard deviation of 9V.
If the observed value of the signal plus noise is 19V, find the best estimate of the signal amplitude.
In a stormy sea, the following waves are present
