Worksheet name | Description |
---|---|

Calculating Fault Current Magnitude in Mathcad | This worksheet shows you how to compute bus faults on power systems. Most faults in power systems occur at points on the line some distance away from the substation bus. |

Load Flow Calculations | This worksheet using PTC Mathcad shows you how to describe the network for a five-bus power system, using a matrix containing the transmitting and receiving bus numbers, the series impedance, and shunt admittance. You can also capture shunt data and bus data in matrices. |

This worksheet using shows how you can use Mathcad to model SAW sensors in aerospace vehicles. The lack of support for transcendentals within the Differential Algebraic Equation framework prevents the use of the frequency domain analysis in analog extended Hardware Description Languages (HDLs). | |

RLC Circuit Analysis | This worksheet using PTC Mathcad includes an example of an engineer designing a hi-fi speaker that must meet a certain frequency response. The horizontal trend must be over the whole spectrum of the audible range with a tolerance of +/- 1dB. |

Theory of the Capacitor revised | This worksheet will solve a common 2-circuit physics problem to determine charges and energy, keeping in mind the Reciprocal System Theory and the conventional theory. |

Three Phase Power System in PTC Mathcad | This worksheet discusses how to find the power distribution and parameters for power lines. Unbalanced power systems require analysis by the method of symmetrical components. |

Cross Talk of a Signal Between Copper Traces | Dimensions and geometry of the 2 selected copper traces are typed into Mathcad so that the cross talk associated with a signal sent through the traces can be calculated. This will enable the Design Testers to verify the cross talk is within the acceptable range as defined in the Design Requirements. |

Impedance Calculation Along a Copper Trace | Dimensions of the selected copper trace are typed into Mathcad so that the impedance associated with a trace can be calculated. |

Propagation Delay of a Signal Along a Copper Trace | Dimensions of the selected copper trace are typed into Mathcad so that the propagation delay associated with a signal sent through the trace can be calculated. This will enable the Design Testers to verify the propagation delay is within the acceptable range as defined in the Design Requirements. |

Voltage Drop Calculation | This worksheet will enable Design Testers to verify the voltage drop is meeting the Design requirements. Constants for resistance from CRC Handbook of Chemistry and Physics, 57th Edition, 1976-1977, CRC Press, p. F167-168. |
