Jens-Michael Gross11 年多前in reply toblb Guru227245points blb 说: You have a 1.5 volt reference with a 10 bit ADC. So divide 1.5 by 1024 Actually by 1023. as 0 is 0V and 1023 is Vref. So each count is 1/1023 of Vref. However, usi...
Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
The ADC’s sampling rate is set to 62.5 kHz or 1 MHz, and the average value register of the ADC is configured to 4096 or 65536. The output rate remains fixed at 15 Hz. Three samples are averaged to yield one data point (resulting in a 5 Hz, 10 PLC reading rate). A total ...
How to calculate the expected billing amount for the advertisement by keyword and system for implementing the methodPROBLEM TO BE SOLVED: To disclose a method for calculating a predicted charge amount for advertisement for each keyword and system for executing the method.宋 基 豪...
Using the Nernst equation, one can calculate the EMF produced under a no-load situation: Where E is the Nerstian EMF generated, R is the Universal Gas Constant = 8.31 J*K-1*mol-1, T is the temperature of the cell in Kelvin, F is the Faraday Constant = 96500 Cmol-1, Z is the ...
Rogowski coils induce a voltage that is proportional to the rate of change of Current and thus require in integrator circuit to convert to proportional current. The integrator is a separate box/component that is usually panel or DIN rail mounted, requires a DC power supply, and outputs low ...
Powered mixers offer most of the bells and whistles you’ll find on unpowered mixers in terms of routing options, effects processing, EQing, and much more. As with any mixer purchase, you’ll need to calculate the total inputs and outputs you need as well as the necessary power to drive...
How can you know the best sampling rate to be used during analog-to-digital conversions to have the best storage/quality balance? The answer is the Nyquist Theorem. This theorem states that the sampling rate on analog-to-digital conversions must be at least two times the value of the highes...
A device with 0.5LSBs of INL can give 0.0122% error or 13 bits of accuracy (with gain and offset errors removed). To calculate best-case accuracy, divide the maximum INL error by 2N, where N is the number of bits. In our example, allowing 0.075% error (or 11 bits) for the ADC ...
Knowing the sample rate, calculate 10 × log (fSAMPLE/2). Determine the converter's noise power in a 1Hz bandwidth by subtracting (4) from (3). Calculate KTB for B = 1Hz (equal to -174dBm at room temperature). Subtract KTB from the normalized Nyquist band noise power to determine the...
