Hi, I want to know what is the proper methods to prolong lithium battery life:
When Should I recharge the battery(at any level 90%, 70 or 40 etc)?
Should I charging it fully at 100%?
is true that discharging battery below 20% once each month is useful to boost battery life?
i know that i am using the hard way, i do that because my supervisor want me to do that.
the main noise is come from electrical 50 Hz, even when i removed it, the noise still large value(about 0.1 to 0.2 V)
yes i want to record a row data.
yes i understand the aliasing issues , i will...
ok, let me explain:
ECG signal is obtained by using preamplifier as figure below:
i want to record ECG signal but without using preamplifier, first i will record the two signals come from right and left arms, then inside the computer(by using matlab) i will obtain the ECG signal...
yes i read it, i understand that this chip use one ADC for each channel
i am not sure, but may be i need about 1 micro second difference between sampling the two signals
not less than 200 Hz.
i will search for these questions
OK, if ADC "simultaneous sample and hold" of 20 bits is unavailable:
can i use two ADC chips, to record the two signals?
can i ensure that the two signals will be sampled in the same time exactly?
Hi:
I need to record a two analog signals, by using an ADC(of 20 bits resolution or higher), the two signals are very weak signals of signal to noise ratio about -30 db, so the two signals are very effective by the noise.
the problem is : how to record these two signals at the same...
I read information said that:
the turing machine can only execute one program
the universal turing machine is Re-programmable machine
the information here:
http://www.cs.rpi.edu/~moorthy/Courses/modcomp/slides/Universal_Turing.ppt
yes that help,
but if the turing machine can execute any "program",
that mean it can simulate any other turing machine ,
so that mean any turing machine we can called it universal turing machine!
Hi:
I read many articles about turing machine,but i still confused:confused:
is a turing machine can only execute one program(hardwired) ?
or it can execute many programs(like a conventional computer)?
i asking about turing machine as shown in figure blew(not asking about universal TM...
i will give example:
if we use the direction of Electron spin to represent the Qubit,spin up= 1 spin down=0
each electron could be spin up and down simultaneously (two states at the same time)
but if we have 3 Qubits, we will get a 8 states simultaneously ,
that mean each Qubit has a 8...
