Astromania 2" Moon / Skyglow Filter

Astromania 2" Moon / Skyglow

The filter is a multi-band pass filter which transmits a high percentage of light in the visual spectrum. It will enhance contrast when observing brighter objects such as the moon and planets and in the same time will suppress sky glow from artificial lighting and background reflected glow. The filter has a mild effect of darkening the background of the night sky so that the fainter objects will be against the dark background, excellent for observing planets. The filter will fit all standard sized 2" eyepieces and accessories such as Barlow lens etc. It is mounted in a nicely anodized Al alloy housing and is threaded on both sides for stacking with other 2" filters if necessary.

Bandpass Sigma Delta Modulators: Stability Analysis, Performance and Design Aspects

Bandpass Sigma Delta Modulators: Stability Analysis, Performance and

Sigma delta modulation has become a very useful and widely applied technique for high performance Analog-to-Digital (A/D) conversion of narrow band signals. Through the use of oversampling and negative feedback, the quantization errors of a coarse quantizer are suppressed in a narrow signal band in the output of the modulator. Bandpass sigma delta modulation is well suited for A/D conversion of narrow band signals modulated on a carrier, as occurs in communication systems such as AM/FM receivers and mobile phones. Due to the nonlinearity of the quantizer in the feedback loop, a sigma delta modulator may exhibit input signal dependent stability properties. The same combination of the nonlinearity and the feedback loop complicates the stability analysis. In Bandpass Sigma Delta Modulators, the describing function method is used to analyze the stability of the sigma delta modulator. The linear gain model commonly used for the quantizer fails to predict small signal stability properties and idle patterns accurately. In Bandpass Sigma Delta Modulators an improved model for the quantizer is introduced, extending the linear gain model with a phase shift. Analysis shows that the phase shift of a sampled quantizer is in fact a phase uncertainty. Stability analysis of ...

Fundamentals of Electronics: Book 3: Active Filters and Amplifier Frequency Response (Synthesis Lectures on Digital Circuits and Systems)

Fundamentals of Electronics: Book 3: Active Filters and

This book, Active Filters and Amplifier Frequency Response, is the third of four books of a larger work, Fundamentals of Electronics. It is comprised of three chapters that describe the frequency dependent response of electronic circuits. This book begins with an extensive tutorial on creating and using Bode Diagrams that leads to the modeling and design of active filters using operational amplifiers. The second chapter starts by focusing on bypass and coupling capacitors and, after introducing high-frequency modeling of bipolar and field-effect transistors, extensively develops the high- and low-frequency response of a variety of common electronic amplifiers. The final chapter expands the frequency-dependent discussion to feedback amplifiers, the possibility of instabilities, and remedies for good amplifier design. Fundamentals of Electronics has been designed primarily for use in an upper division course in electronics for electrical engineering students and for working professionals. Typically such a course spans a full academic year consisting of two semesters or three quarters. As such, Active Filters and Amplifier Frequency Response, and the first two books in the series, Electronic Devices and Circuit Applications, and Amplifiers: Analysis and Design, form an appropriate b...
