Abstract: 1483735 Oscillators employing acoustic wave devices; automatic frequency control DEFENCE SECRETARY OF STATE FOR 7 Nov 1974 [9 Nov 1973] 52237/73 Headings H3U and H3A An acoustic wave device for providing a feedback loop for an amplifier to form an oscillator 1, comprises input and output transducers arranged on a substrate to constitute a delay line, and a discriminator 2 which comprises at least one further transducer on the substrate arranged to receive acoustic waves from the input transducer and to produce a control signal, the magnitude of which varies with oscillator frequency and which is fed to phase-shift circuitry in the feedback loop. The discriminator output is taken from a first differential amplifier 22 and applied to a second differential amplifier 3 which may also receive a voltage Vm, the output of amplifier 3 being connected to the phase-shift circuitry. As shown, surface waves are employed but it is envisaged that bulk waves could alternatively be used in which case damping material is applied to the substrate surface. In a first embodiment, Fig. 3, the delay line is constituted by transducers T 3 , T 4  and the discriminator 2 by transducers T 1 , T 2  which are equidistant from T 3  and whose centre frequencies respectively lie above and below that of the oscillator so that near the oscillator frequency the difference of the outputs of T 1 , T 2  varies linearly with frequency. The transducers T 3 , T 4 , which are connected to oscillator amplifiers 18, 19 are arranged as disclosed in Specification 1,451,326 to provide strong mode selection. In use Vm is preferably a modulating voltage and, providing the responses of the differential amplifiers are sufficiently fast, the oscillator frequency varies linearly with Vm. Alternatively, to achieve frequency locking of the oscillator, amplifier 3 may be by-passed, or Vm held at zero. The discriminator may comprise only a single transducer (Fig. 7, not shown) in which case either a voltage (Vc) is applied to one input of differential amplifier 22, or amplifier 22 is by-passed. In an alternative embodiment, Fig. 6, the delay line has two output transducers T 5 , T 6  spaced by one quarter of a wavelength and connected to the oscillator amplifier 27 via phaseshift circuitry including diodes 23, 24 which act as variable resistor means. The output of differential amplifier 3 is applied via an inverting amplifier 30 to diode 24 and via a non-inverting amplifier 31 to diode 23.
