<p>Signal processing by means of a system comprising an elastic wave device, invariant with the temperature. The input signal Se is written into a memory at the timing of a fixed clock he and read at the timing of a clock HL supplied by a slaved generator, which also supplies the signals particularly for modulation to an interface circuit. The signal is applied to an elastic wave device which supplies a processed signal S3 applied to a second interface circuit and to a second memory. The slaved generator also supplies the demodulation signals to the second interface circuit and the writing clock signals HE of the second memory, which is read at the fixed clock timing hL. The slaved generator comprises a basic driver formed by a surface elastic wave oscillator constructed with the same substrate as that of the elastic wave processing device.</p> |
