Transistorized Log-Period Amplifier

Transient Distortion in Transistorized Audio Power Amplifiers

This paper discusses a new kind of distortion mechanism found in transistorized audio power amplifiers. It is shown that this distortion arises from the multistage feedback loop found in most high-quality amplifiers, provided that the open-loop transient response of the power amplifier is slower than the transient response of the preamplifier. The results of the analysis are verified by measure...

TURN-BY-TURN BPM ELECTRONICS BASED ON 500 MHz LOG-RATIO AMPLIFIER

Log-ratio processor working at 500MHz applied to turn-by-turn beam position measurement was implemented. The processor circuit consists of two logarithmic amplifiers and a subtraction circuit. The output value is proportional to beam position. Before, the upper usable frequency of logarithmic amplify is lower than 500MHz. At present, several manufacturers support higher upper usable frequency o...

StUSPACE(log n) <= DSPACE(log²n / log log n)

We present a deterministic algorithm running in space O ? log 2 n= log logn solving the connectivity problem on strongly unambiguous graphs. In addition, we present an O(logn) time-bounded algorithm for this problem running on a parallel pointer machine.

Bandwidth selection method for bias-reduced log-period gram estimator in decaying spectral density

The log-log LMS algorithm

This paper describes a new variant of the least-mean-squares (LMS) algorithm, with low computational complexity, for updating an adaptive lter. The reduction in complexity is obtained by using values of the input data and the output error, quantized to the nearest power of two, to compute the gradient. This eliminates the need for multipliers or shifters in the algorithm's update section. The q...
