“…It is used in various situations where signals of different volumes (usually from different sources) are present. A typical example is that of telephones or cell phones [1], but it is also used for controlling the amplitude of interfering signals using lasers [2] or in pacemakers [3]. Every case is special, however, thus our sensor-based environment also has its special requirements, which should be considered when developing applications for them.…”

Abstract-Wireless sensors are small-capacity devices with low consumption. Their capabilities already exceed the limit required for telephone-quality audio recording and processing, which calls for porting a number of speech processing applications. To do it, however, dynamically adjusting the sensitivity of their microphone is vital, which is called Automatic Gain Control (AGC). In this study we employed two simple algorithms for this task and will show that they can indeed be very effective in distant recording conditions, especially as it requires techniques which have low computational requirements.

In the phase-shift measurement method, the distance traveled by light can be obtained on the basis of the phase difference between the reference signal and the measured signal. When a different colored object is measured, the intensity of the measured signal varies greatly, even at the same distance, which causes a different phase delay owing to the wide dynamic range input into the signal processing circuit. In this study, an intensity control method is proposed to solve this phase delay problem.
