17 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.

18  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.
