Re: impulsive noise
You can modelate it with a Poisson's process. This process have an input with this form:
z(t)=∑δ(t-ti)
because the process is activeds by a secuence of impulses ocurring at random times ti.
You need the set of Poisson points ti, with average λi and a real function h(t)...
Re: Sampling theorem
The theorem of the sampling establishes that the demuestreo frequency must be - to the less twice frequency of the signal original-but this sampling is ideal. The accomplishment of the sampling is with signals delta of Dirac.
The sampling that takes place in the reality is...
hp33120 specification
I believe that this problem would not have to happen, can be a problem of the resolution of the oscilloscope.
It can that depends on the load to which these applying the signal, if this is next to a short circuit for example.
You can see the specification in this pdf.
mealey state machine
In this diagram parts of a rest state (S0), it is very common to include an initial state in these machines, if it once give account you uprooted the robot, does not become to this state.
Based on the value of the entrance you pass to a state or another one, thus if he is a...
All the microcontrollers who I know that they have an integrated module I2C, have it in form registry.
If your you pay attention all the microscontroladores with similar modules of communications (SPI, sci...) the data write on a registry so that you can operate based on the received data, if...
Re: Casuality
A signal is causal when its value is null for moments of time t<0 (or n in discrete time).
In order to know if the signal is causal only you must know the value this one just before applying it. If he is different from zero, the signal is causal.GFor example, in an electrical...
dbm to mv
You can't convert mV to dB because dBs are an adimensional magnitude, like the quotient of two powers or two tensions. Thus, L(dB)=k.log(x2÷x1) where k is 10 for the powers and 20 for voltages.
I think you can use this equation L(dBm)=10log(p(mW)/1mW), like a mW is as to power...
If the error happens only with a particular .m file it means that you have a syntax error or another similar thing. Although it produces an output, it´s could be bad if it´s depends of bad code (i.e if you call a fuction and then you don´t use the output of this). I think that you could prove to...
A possible solution is the use of an integrated circuit that realize only this function and that your you only can control with the microcontroller.
A device example is the DS1050. As it is controlled with bus I2C you can arrange up to 8 in your application. There are many devices of this...
If you want a greater reaches of the IR's emision you can use this circuit. The transistor must works in saturation in order to transmit and works in the region of cut to not transmit.
One of the peculiarities of one varactor is that if the voltage in his extrems increases then the resistance of the varactor below and viceversa.
The use of this characteristic allows to make constant the current that circulates in a resistance ready in parallel with varicarp. In the...
