CHAPTER 5 Improvement: - Simulation for the old circuit Triangle-to-Sine wave conversion by using spice technique (Microcap V6). The old technique used the amplitude in mV. The result of this simulation has shown good agreement with the provided lab-result. 1-Triangle to Sine wave converter by using transistor

Conclusion The importance of triangle to sine wave converters stem from the fact that triangular waveforms are easier to generate. Triangular waveforms are generated from pulse (square wave) generator by integrating the square wave. The BJT, which has the smallest error than any other technique. Also, the angular range could be increased by one π for each addition of the transistor.

The MOSFET, which has the advantage that it can be applied to synthesize any odd function. The nonlinear technique as a whole has the advantage that we could get an offset output voltage which appears as a phase shift associated with the output signal. For high frequency the techniques are not work good. In old Bipolar technique the amplitude should be small. The advantage of Seven Segment technique Triangle-to-Sine wave that its ability to increase the operating voltage from1.8-15v.
