By doctorj, on July 17th, 2009% Here is an example solving an ordinary differential equation using the method of Separable Variables. The example uses a trigonometric identify as well as integration by parts to find the solution to the given differential equation. . . . → Read More: Differential Equation Tutorial Video – Initial Value Problem Using Separable Variables (Example 4)
By doctorj, on July 15th, 2009% Sensors or transducers monitor, measure, and control physical processes as key elements of instrumentation systems. A transducer device converts a physical variable such as temperature, pressure, light or motion into an electrical signal such as voltage and current. Electrical signal processing converts the transducer output as required for the rest of the instrumentation system. What [...] . . . → Read More: Operational Amplifier (Op Amp) Application – Transducer Interface Circuits – Part 1
By doctorj, on July 9th, 2009% This concludes the series of tutorial videos on the R-2R ladder network circuit as an example of operational amplifier design and applications. The video will continue to discuss the 4-bit digital-to-analog converter (DAC) and R-2R ladder circuit using the superposition principle to analyze the DAC. After viewing the above video on the R-2R digital-to-analog converter [...] . . . → Read More: OpAmp Design & Application Tutorial – Digital-to-Analog Converter (DAC) Circuit R-2R Ladder – Part 5
By doctorj, on July 8th, 2009% A series of videos on opamp design and applications will continue with the analysis of the digital-to-analog (DAC) R-2R ladder network. As before, the video will discuss the R-2R DAC circuit and analyze it using the concept of superposition. A four-bit binary input was given as an example. The next video will conclude the analysis [...] . . . → Read More: OpAmp Design & Application Tutorial – Digital-to-Analog Converter (DAC) R-2R – Part 4
By doctorj, on July 7th, 2009% Here, we have an op amp implementation of the binary-weighted summer known as the R-2R ladder digital-to-analog converter (DAC). The advantage of this circuit is that there is not a requirement to have a wide range of different resistor values as found in the binary-weight DAC. We’ll again use 4-bit digital input as an example [...] . . . → Read More: OpAmp Design & Application Tutorial – Digital-to-Analog Converter (DAC) R-2R Ladder – Part 3
