Comments, with reply, on "A simple technique for analog tuning of frequency synthesizers" by J.P. Hauser

The commenter points out that an analog implementation of the fractional N phase-locked loop variable frequency synthesis technique described by J.P. Hauser (ibid., vol.38, no.6, p.1141-4, 1989) results in a novel minimization of active hardware, but that there are significant performance compromises. The original author's reply is included.<
