Sine to Square Wave
Conversion of triangle wave shapes to sinusoids is usually accomplished by diode-resistor shaping networks, which accurately reconstruct the sine wave segment by segment. Two simpler and less costly methods may be used to shape the triangle waveform of the 566 into a sinusoid with less than 2% distortion. The non-linear IDSVDS transfer characteristic of a P-channel junction FET is used to shape...
Two pairs of MOSFETs form a bridge that alternately switches current in opposite directions. Two parallel-resonant LC circuits complete the converter. The Ll/C1 combination is resonant at the fundamental frequency; the L2/C2 combination is resonant at the clock frequency"s third harmonic and acts as a trap. Tl and C3 ensure that both halves of the MOSFET bridge are never on at the same time...
Sine Wave To Square Wave Converter Circuit
This circuit turns a sine wave into a square wave. It is comprised of a single 2-input NAND Schmitt trigger that`s configured as an inverter with a trigger level adjustment at its input. As the input voltage rises above the gate`s trigger point,

Square wave-to-triangle converter
This fixed frequency triangular waveform generator driven by a TTL square wave generates typically 16-V p-p triangles at frequencies up to several MHz. It uses only one AND open collector gate, or one open collector inverter as a fast integrator with gain. Careful successive adjustments of R and PI are needed. When correct adjustments are reached, output amplitude and linearity are largely...

Self-powered Sine to Square wave Converters
This circuit is intended to provide good square waves converting a sine wave picked-up from an existing generator. Its major feature consists in the fact that no power-source is needed: thus it can be simply connected between a sine wave generator and the device under test. The input sine wave feeds a voltage doubler formed by C1, C2, D1 & D2 that

SINE WAVE TO SQUARE WAVE CONVERTER
This circuit tums a sine wave into a square wave. It is comprised of a single 2-input NAND Schmitt trigger that`s conftgured as an inverter with a trigger level adjustment at its input. As the input voltage rises above the gate`s trigger point, the output snaps to its alternate state, producing a square-wave output.

The circuit can be used as the signal source of calibration level meter or sensor-driven differential transformer. Circuit oscillation frequency is determined by the 74HCO4, and it is transferred lkHz by R. The supply voltage of Tl changes with the amplitude output. The switch turns the output voltage into square wave, then it will get sine wave b
Time-tag impulses & zero-crossing
Figure 1 shows the typical output from a spectroscopic amplifier, where the presence of a large amount of detector noise with Gaussian distribution is a limiting factor for system performance in amplitude and timing resolution. The time-tagging of such pulses is subject to two well-known types of errors: the jitter related to the noise and the "walking time" arising from the amplitude variation...
Sawtooth to triangle converter for oscillator
This wave shaper needs an input saw that goes from Vss to (ideally) Vdd. It works well with the 4069 VCO designed by Ren? Schmitz. Any saw will work as long as the wave is centered halfway between the rails. It works as follows: The upper set of 2 linear mode gates provide an inverted and noninverted copy of the saw. The 3 logic gates at the bottom provide a sort of comparator that switches at...
Zero crossing Detector
This Circuit is a zero crossing detector, which produces an output state change whenever the input crosses the reference input. In this case the reference input is connected to ground. The output of the comparator can easily drive multiple outputs, which can include, for example, a relay, acontrol gate and a LED indicator.

Generating sine from square wave
Generating a true sinewave from an input square wave over an octave in frequency is not simple. A sinewave oscillator would be easy. Filtering to the fundimental would be easy for a frequency range less than an octive. The best I was able to come up with is the attached circuit which approximately generates the sine of the input voltage. Integrating the squarewave to a triangle...
