Which calculator is best for postgraduate electrical engineering studies?

Click For Summary
SUMMARY

The discussion centers on selecting the best calculator for postgraduate electrical engineering studies, particularly in communication and computer networks. The Texas Instruments TI-89 is recommended as the most suitable option due to its advanced features, despite its higher price of approximately $140. The TI-36X is suggested as a budget-friendly alternative at $10, suitable for basic engineering calculations and legal for FE and PE Exams. The TI-Nspire™ CX CAS is considered less optimal than the TI-89 for the user's specific needs.

PREREQUISITES
  • Understanding of electrical engineering concepts
  • Familiarity with MATLAB and Excel for computations
  • Knowledge of calculator functionalities, particularly for engineering
  • Awareness of FE and PE Exam requirements
NEXT STEPS
  • Research the features of the TI-89 and TI-89 Titanium calculators
  • Explore the capabilities of the TI-Nspire™ CX CAS for engineering applications
  • Investigate the use of MATLAB for engineering calculations
  • Learn about RPN calculator apps and their advantages for engineering tasks
USEFUL FOR

This discussion is beneficial for postgraduate electrical engineering students, electrical engineers, and anyone involved in communication and computer networks who seeks to optimize their computational tools.

HI
I need your advice to buy a calculator to be used in master study in electrical engineering-communication and computer networks and also useful as an engineer (electrical engineer/Electronics & Communication)
Thanks in advice

TI-89

that being said I rarely use a calculator anymore. I use matlab/excel for 99% of my computation
 
Yep, TI-89 is the ticket. A little pricey at $140 or whatever, but worth it.

You can buy a "secondary" calculator, the TI-36X for $10 that works pretty well for engineering as long as you don't need graphs, matrices, multivariables or integrals solved. TI-36X is also legal on the FE and PE Exams.
 
Thanks
what about TI-Nspire™ CX CAS is it or TI-89 Titanium
 
The Ti-89 is better for your needs than the Ti-nspire CX CAS. At your level, you could go cheap ie Ti-36X pro and an Android or I-pad app or cheap software alternative as well.

The Ti-89 also comes with EE-Pro or it is free to download for a Ti-89. That software used to cost Hp calculator owners around $100 before Ti bought the software out and took it away from the Hp market.
You might consider an Hp 50G, but you should play with an RPN calculator app before you spend real money on one.

Any classical scientific calculator should be more than enough... if you know how to use it.
