ResumoThe Wien bridge oscillator circuit is generalized through the addition of two resistors, and it is shown that an appropriate choice of these leads to single resistance control of the frequency of oscillation over a, theoretically, wide range. The limitations of the scheme are discussed and the range of frequencies obtainable in practice is indicated.
