A standardized frequency response curve(or contour) for recording of phonograph records, notably with attenuation of bass frequencies during recording to reduce the excursion of the cutting stylus, permit closer spacing of record grooves, and increase possible recording time, together with a compensating contour with bass boost for use at playback time.  3, record 1, English, - RIAA%20curve

British made Search And Rescue And Homing(SARAH) beacon SRI 23006 was a UHF rescue beacon comprising speech unit, transmitter/receiver unit, coding unit and combined LT/HT battery. The first three units are permanently interconnected. Attached to the transmitter/receiver unit is a leaf spring aerial which fold up to very small dimensions. The SARAH beacon has three modes of operation. In the normal beacon condition pulses on a frequency of 243 MHz are being automatically transmitted. The pulses are transmitted in a rate of 210 pairs per second, the spacing between the pulses in each pair is determined by the coding unit and is a distinguishing feature between the beacons.(Note that the normal beacon operation has much in common with the war-time developed "Walter" beacon). The peak power in this mode is 15 watts and the battery life is about 20 hours continuous operation.  1, record 2, English, - search%20and%20rescue%20and%20homing%20beacon

A cepstrum is a spectrum of a logarithmic power spectrum. Because of this, a peak in the cepstrum indicates periodicity in the spectrum; usually, this signifies a family of harmonics at equal frequency intervals.  1, record 3, English, - cepstral%20analysis

Cepstral analysis has been widely applied to gear monitoring. The cepstrum is well suited for the detection of sidebands in vibration spectra and for the estimation of their evolution during gear life. In addition, since the cepstrum estimates the average sideband spacing over a wide frequency range, it allows very accurate measurement of the sideband periodicity. It is therefore applicable to both detection and diagnosis of gear faults.  2, record 3, English, - cepstral%20analysis
