Frequently Asked Questions
What exactly is EMI?
EMI, or “Electromagnetic Interference,” is the unwanted impairment of electronic equipment from another electrical or electronic source, natural or man made. Examples include the following:
- Jamming of radio or television communications due to nearby computers or other electronics
- Jamming of sensitive electronics (such as medical devices or factory controls) due to nearby radio transmitters
- Unexpected computer or control system resets Electrostatic Discharge (ESD) from humans.
- Computer malfunctions due to disturbances on the power lines
- Equipment damage due to a lightning strike on the power lines
What is EMC, and how is it different from EMI?
EMC, or “Electromagnetic Compatibility,” implies the successful operation of electronic equipment in the intended electromagnetic environment. In short, EMC is the solution, while EMI is the problem. Both terms are commonly used in the electrical engineering community.
What is RFI?
RFI, or “Radio Frequency Interference,” is an older dated term for EMI. It harkens back to the time when most EMI problems affected only radio transmitters and receivers. It is now used to describe the specific problems that may occur when using a radio transmitter near another sensitive electronic device. These problems can occur with medical devices, industrial controls, computer and control systems, and other electronic systems.
Can EMI be measured?
Yes. If EMI is suspected, a “site survey” can be conducted to measure typical RFI levels, as well as power disturbance levels. Since this is like taking a snapshot, it may miss intermittent problems, but it can capture continual problems, such as the levels from a nearby broadcast radio or television stations.
Are there government regulations on EMI?
Yes. The specific tests and test levels vary depending on the equipment and the environment (home, business, factory, hospital, aircraft, automobile, military, and more.) The tests are designed to minimize problems in actual operation, but do not guarantee that EMI problems will never occur. “Site surveys” can help determine is the actual environmental levels exceed the test requirements.
Will EMI problems continue?
Yes, and they will likely get worse in the future. This is due to both faster electronics, combined with the wide proliferation of electronic systems (cell phones, home computers, electronic devices and control systems.). EMI is a price we all pay for using advanced complex electronics in our lives.
Forensic Accounting FAQs (Pappas & Company -Forensic Accountants)
What is a forensic accountant?
The word forensic is generally defined as belonging to the courts of justice. An accountant is an expert in the field of accounting, a method for preparing financial record of business transactions and statements concerning the assets, liabilities and operating results of a business. By combining these two concepts, a forensic accountant becomes an expert in accounting theories and application in relation to legal principles and cases.
Typically, a forensic accountant makes an intense analysis of one particular incident or series of events to determine if it can be supported by generally accepted accounting principles, and to defend or refute this procedure in a courtroom.
What types of services can a forensic accountant provide?
What are common areas of litigation in which a forensic accountant is engaged?
When you hire a forensic accountant, what are you hiring him for? What do you think his job is?
Our job is to find and advocate the truth and to communicate it to you so that you are not surprised and so that it will help you in your case, even if the truth does not support your position.
What are some advantages to hiring a forensic accountant as early as possible in the litigation process?
Mitigate potential for additional hiding and/or theft of assets
Time limits on obtaining information, ex. Subpoenas for bank records
More efficient – less risk of duplicating efforts – efforts can be directly related to the issue instead of clerical
Obtaining information can be time consuming, ex. Court certified tax returns and K-1s
