Bainter Notch Filter: Design and Tuning

This article reviews the theory and implementation of the Bainter Notch Filter. Written and developed by  Basin Street Design. This calculation examines the effectiveness of a Bainter notch filter such as the Bainter circuit as seen in the figure below [1]. Low-pass, high-pass, and standard notch responses can be realized. The following picture shows the […]

Wien Bridge Oscillator: Unbalanced and Balanced

This article reviews the theory of the Wien Bridge Oscillator. Written to support his own practical projects by Basin Street Design. Here is the famous Wien Bridge oscillator circuit [1]. This picture is one shamelessly stolen from somewhere on the interwebs and modified for my purposes: The oscillator operates by sending part of its output […]

Magic Eye: Emulation with Arduino

“Magic Eye” emulation project written and developed by Konstantin Dorohov (USA). The recorders and receivers of my youth used the now defunct tube level indicators or “magic eye” on 6E1P or 6E5C lamps. Now is the time for nostalgia for the “old days” and you can buy assembled indicators on aliexpress or amazon. They are […]

Group Velocity: Mathematical Proof

The term group velocity defines the rate at which the envelope of a signal propagates in a transmission medium. This signal transmitted over the medium is obtained when a modulating signal modulates a central frequency, typically called the carrier [1]. As a result, the modulating signal and the envelope are equivalent. While the envelope propagates […]

Frequency Constant Phase Shift and Distortion

Transmission media and electronic components can have multiple effects on the signals propagating through them [1] [2]. To avoid phase distortion, it is necessary that the phase of the system, the phase shift introduced by the medium, is linear with frequency. This case, whose effect consists of a time delay of the signal, is often […]

The Mathematics of Linear Distortion

The mathematics of linear distortion only applies to linear and time invariant systems [1] [2]. Therefore, these systems and their translation to the frequency domain, where the mathematical analysis is simplified, are briefly summarized. Then it is discussed how the presented theory can be applied to real transmission media and/or electronic components. Finally, the mathematics […]

Semiconductor Industry

Semiconductors are materials that can behave as conductors or insulators depending on the environmental conditions. They are very relevant materials since they are the basis for the emergence and development of modern electronics (the transistor) and for the manufacture of integrated circuits. Hence the importance of the semiconductor industry. Semiconductor Industry Applications Today, electronics is […]

Bitcoin Objective Value Caculation

1. Introduction Bitcoin objective value is difficult to establish. Actually, like so many other questions in economics, it depends on the perspective from which it is calculated. Therefore, estimates can be found that treasure very different values ​​for bitcoin, from zero to millions of dollars. Likewise, the calculation method used in this article simply reflects […]
