Abstract

An ultra-linear ramp generator having separately programmable ascending and decending ramp rates and voltages is provided. Two constant current sources provide the ramp through an integrator. Switching of the current at current source inputs rather than at the integrator input eliminates switching transients and contributes to the waveform precision. The triangular waveforms produced by the waveform generator are characterized by accurate reproduction and low drift over periods of several hours. The ascending and descending slopes are independently selectable.

Precision triangular waveform generator model 79-11965

Technical Report Mueller, T R

A signal generator is described that will produce a quasitriangular waveform that is reproducible over long periods of time. Each of the two sides of the triangle that represent amplitude are linear with respect to time, but the apexes are not points because of finite system response. The ascending and descending slopes are independently selectable. The high precision arises from the use of low-drift amplifiers and low-temperature-coefficient components. Amplitude-time jitter is less than +- 10 ..mu..s for periods of several hours. This report includes a circuit description, operating procedures and instructions, and a checkout and test procedure. Circuit diagrams, andmore » photographs are included. « less
Tone signal generator for producing multioperator tone signals using an operator circuit including a waveform generator, a selector and an enveloper

Patent Dong, Q; Jenkins, M V; Bernadas, S R

A frequency modulation (FM) tone signal generator for generating a FM tone signal is disclosed. The tone signal generator includes a waveform generator having a plurality of wave tables, a selector and an enveloper. The waveform generator furnishes a waveform signal in response to a phase angle address signal. Each wave table stores a different waveform. The selector selects one of the wave tables in response to a plurality of selection signals such that the selected wave table largely provides the waveform signal upon being addressed largely by the phase angle address signal. Selection of the selected wave table variesmore » « less
A Novel Phase-Coherent Programmable Clock for High-Precision Arbitrary Waveform Generation Applied to Digital Ion Trap Mass Spectrometry

Journal Article Koizumi, Hideya [ORNL]; Jatko, William Bruce [ORNL]; Andrews, Jr, William H [ORNL]; ... - International Journal of Mass Spectrometry

Digital ion trap (DIT) mass spectrometry requires the ability to precisely and accurately produce waveforms. The quality of the mass spectra produced in terms of resolution and mass accuracy depend on the resolution and precision of the applied waveforms. This publication reveals a novel method for the production of arbitrary waveforms in general and then applies the method to the production of DIT waveforms. Arbitrary waveforms can be created by varying the clock frequency input to a programmable read only memory that is then input to a digital-to-analog converter (DAC). The arbitrary waveform is composed of a defined number ofmore » « less

Agile high resolution arbitrary waveform generator with jitterless frequency stepping

Patent Reilly, Peter T. A.; Koizumi, Hideya

Jitterless transition of the programmable clock waveform is generated employing a set of two coupled direct digital synthesis (DDS) circuits. The first phase accumulator in the first DDS circuit runs at least one cycle of a common reference clock for the DDS circuits ahead of the second phase accumulator in the second DDS circuit. As a phase transition through the beginning of a phase cycle is detected from the first phase accumulator, a first phase offset word and a second phase offset word for the first and second phase accumulators are calculated and loaded into the first and second DDSmore » « less

Low frequency ac waveform generator

Patent Bilharz, O W

Low frequency sine, cosine, triangle and square waves are synthesized in circuitry which allows variation in the waveform amplitude and frequency while exhibiting good stability and without requiring significant stablization time. A triangle waveform is formed by a ramped integration process controlled by a saturation amplifier circuit which produces the necessary hysteresis for the triangle waveform. The output of the saturation circuit is tapped to produce the square waveform. The sine waveform is synthesized by taking the absolute value of the triangular waveform, raising this absolute value to a predetermined power, multiplying the raised absolute value of the triangle wavemore » « less
