With this voltage controlled sawtooth oscillator there is the opportunity to explore the application of the LM311 comparator, a constant current source using a single transistor, how to make a transistor to switch faster, what are the factors that affect the frequency range and in general, what to care about in the circuit for higher frequencies and wide bandwidth.
A sawtooth waveform generator such is useful in several testing applications, particularly for components characterization to drive the volt-amper measurement on an oscilloscope or with a X-Y plotter. Other applications include voltamperometric tests and other experiments in electro-chemistry.
This #VFO for #sawtooth waveform operates at frequencies between 10 Hz and 1 MHz in two bands, with an output voltage of about 4 Vpp.
In this video a the oscillator is part of a larger function generator project, covered in other videos that you can follow watching the full series: youtube.com/watch?v=ye9dguKy_Cs&list=PLwbCeSU2Kq_zORt4un2iQ3JUYxzWF3cTJ
