| Descripción: | Variable frequency oscillators are an essential element of many radio communication systems. One of the problems in their design is the elimination of undesirable variations in the output frequency. Present day knowledge of the causes of frequency instability in oscillators used in radio communication equipment, and of the methods developed to achieve good stability, is thoroughly outlined. The functions required of a variable frequency oscillator, and means of achieving variable frequency output with crystal control are mentioned. The special conditions applicable to very high frequency oscillators are presented. The record is given of an experimental investigation of the frequency fluctuations existing in small, battery operated oscillators operating in the frequency range of 30 to 80 megacycles, and of a procedure suitable for reduction of these variations. The results should be useful in the design of miniature, man-portable transmitters and receivers for short distance communication. |
