The left-hand side is precisely the relationship in Eq. (4.13), if the phase f(t) is set to zero. The Modulation Property states that the new spectrum will consist of two replicas of G( f ), one centered on 2f0 in the negative frequencies and the other on f0 in the positive frequencies. Taking the product g(t) cos 2pf0t thus carries out the most important modulator requirement: Move the baseband signal to a new frequency band. We need to get a better feeling for what the new signals look like. Figure 4.6 at the top shows a piece, g(t), of a randomly varying waveform that has frequencies spread uniformly through the range 25 to 5 kHz. Below it is the same signal, shifted up in frequency by 50 kHz. This is the signal g(t) cos 2pf0t, and it has frequencies spread through the range 45 55 kHz (as with all real-valued time signals, there is also a mirror-image spectrum in the range 245 to 255 kHz). It is easy to see the in uence of a 50 kHz sinusoid in the second picture, but here we must be careful. The signal energy at 50 kHz is in nitesimally small. The

providing their account passwords by forwarding the dial-up lines to a decoy computer that simulates the login process. Depending on the telephone service used within the company, the call forwarding feature may be under control of the communications provider, rather than the telecommunications department. In such circumstances, a request will be made to the communications provider to insure the call forwarding feature is not present on the telephone numbers assigned to dial-up and fax lines. 3-2 Caller ID Policy: The corporate telephone system must provide caller line identification (caller ID) on all internal telephone sets, and, if possible, enable distinctive ringing to indicate when a call is from outside the company. Explanation/Notes: If employees can verify the identity of telephone calls from outside the company it may help them prevent an attack, or identify the attacker to appropriate security personnel. 3-3 Courtesy phones Policy: To prevent visitors from masquerading as company workers, every courtesy telephone will clearly indicate the location of the caller (for example, "Lobby") on the recipient's caller ID. Explanation/Notes." If the caller ID for internal calls shows extension number only, appropriate provision must be made for calls placed from company phones in the reception area and any other public areas. It must not be possible for an attacker to place a call from one of these phones and deceive an employee into believing that the call has been placed internally from an employee telephone. 3-4 Manufacturer default passwords shipped with phone systems Policy: The voice mail administrator should change all default passwords that were shipped with the phone system prior to use by company personnel. Explanation/Notes: Social engineers can obtain lists of default passwords from manufacturers and use these to access administrator accounts.

hormones. Given the wide range and individual variability of testosterone and growth hormone, this caveat closes what could have been a giant loophole. The fourth criterion is that there is no reasonable therapeutic alternative. Although this is sound in theory, with diseases such as diabetes in which insulin is the standard treatment, it becomes more problematic in deciding how far an athlete should go in order to satisfy this condition. For example, in the treatment of ADHD, atomoxetine is approved for this condition and is not prohibited. Is it reasonable to require that every athlete with ADHD have a therapeutic trial of atomoxetine before being granted a TUE for methylphenidate The nal criterion in Table 17.2 is that the need for the medication in question cannot be to treat a condition resulting from past non-therapeutic use of a prohibited substance. By adding this statement, WADA took special precautions to prevent an obvious approach to abusing the TUE process. For example, following the extended use of AAS, particularly long-acting compounds, the pituitarygonadal axis will be impaired, often for several months. An athlete could apply for a TUE to use testosterone on the basis of subnormal testosterone levels. This TUE criterion makes it clear that an athlete could not receive a bene t after such use. The WADA TUE standard outlines a reasonable method for distinguishing legitimate, therapeutic uses from ergogenic uses of prohibited substances. Although every case might not be clear-cut, at least there are guidelines to attempt harmonization and equitable handling of athletes. Physicians can do much to help achieve this by exercising their best professional judgment.
