Amoxicillin is a semi-synthetic penicillin, an analog of ampicillin, with a broad spectrum of bactericidal activity against many gram-positive and gram-negative micro-organisms. It is used in the treatment of: Gonorrhoea

AC '97 (Audio Codec '97) is a specification for an audio system within personal computers developed in 1996 by, among others, Intel, Analog Devices and Creative Labs. AC '97 separates the analog and digital circuits, thereby reducing noise.

In audio-engineering an A/D converter converts analog signals into digital signals. The analog signal is sampled every few milliseconds and its level is quantified into a digital word. The larger the digital word, the more accurate the representation of the analog value.

In audio engineering, aliasing is a form of distortion which can occur during the conversion of analog signals into digital. If the input signal is more than one half the sampling rate, only portions of the signal will be present when the system samples the waveform. A false image of the waveform based on the components that were actually sampled, is created. A system which samples at 48 kHz can correctly process signals of up to 24 kHz. To remove signals above the Nyquist frequency, all A/D converters employ anti-aliasing filters.

Analog is a freeware computer program for analysing http server log files. Analog works on almost any operating system and is designed to be fast and to produce accurate and attractive statistics which provide technical reports about the http server. Analog does not attempt to guess at visitor activity, but reports the facts as recorded in the http log files. This diminishes Analog's usefulness for producing management reports for marketing departments. Analog produces a single page HTML format report which includes graphs and sub-reports. The actual reports produced may be selected and customised through adjustment of the Analog configuration file.

An analog computer represents variables by voltages, and these can be continuously variable.
Analog computers were very popular in the 1950s and 1960s, but the technology of the time was very restrictive. Valve operational amplifiers drifted in an alarming manner and transistor versions required very careful design. The arrival of integrated circuits should have revolutionised
analog computers as cheap, small and stable, but the technology also changed digital computers by increasing their speed to the point where they finally became viable.

Analog Loopback (ALB) is connecting a received analog signal to the return transmitting path; a common test method for locating transmission problems in data transmission systems.
Research Analog Loopback
An analog signal is a signal in the form of a continuous varying in step with the actual transmitted information; attempts to transmit an exact replica of the inputted signal down a communications channel.
Research Analog Signal
Analog Transmission is communications by transmission of continuously varying representations of the input signal, as compared to coded words in digital transmission.

Angle Modulation is refers to the change of angle of a signal that occurs in Frequency Modulation or Phase Modulation communications systems; usually analog.
