Instrumental factors like electronic noise and imperfect analog logarithmic amplifiers have been taken into account.

It consists of a chain of amplifiers, filters and a logarithmic amplifier/detector.

The theory and an experimental verification for the case where the nonlinearity is generated with a logarithmic amplifier is presented.

Engineered around powerful X-band transmitters, they feature logarithmic amplifiers and advanced micro processing technology.

Combining devices, we will build electronic functions such as adders, logarithmic amplifiers, analog-to-digital converters, sine wave generators etc.

Here the AD 8307 logarithmic amplifier from Analog Devices represents an almost ideal component, as a detector with dB linear output.

One variety is a triplet of amplifiers: a logarithmic amplifier, followed by a variable-gain linear amplifier and an exponential amplifier.

Detection of the signal is performed by the logarithmic amplifier/detector, which provides a DC voltage, which is proportional to the logarithm of the incident power density.

Four-decade logarithmic amplifiers have given increased data compression and have allowed standardization of data with that from FACScan and FACStar.

FINAL NOTE: The actual final design of the project discussed in this question was implemented using a single logarithmic amplifier to partially linearize the data (see Fig.1b) and a cubic spline curve fit to account for the remaining non-linearity.

In early cytometers, this was often accomplished even before data acquisition by use of a log amplifier.

A necessary condition for successful operation of a log amplifier is that the input voltage, V, is always positive.

A Log amplifier is a linear circuit in which output voltage is a constant times the natural logarithm of input.

A log amplifier is an amplifier for which the output voltage V is K times the natural log of the input voltage V.

Commonly used amplifiers on signal on conditioning include sample and hold amplifiers, peak detectors, log amplifiers, antilog amplifiers, instrumentation amplifiers and programmable gain amplifiers.

They include two or more transistors on a common substrate to ensure close parameter matching and thermal tracking, characteristics that are especially important for 'long tailed pair' differential amplifiers, current mirrors, log amplifiers.

In addition to the DLVAs, Filtronic produces RF log amplifiers offering improved speed, for detection of fast pulses and much higher dynamic range, also a range of threshold detectors.

Firstly, the control file has a reasonably homogeneous level of background fluorescence, that the data was collected using a four decade log amplifier, and that the sample size was large enough that it is representative of the population.
