The notion of critical bands, introduced by Fletcher (1940), explains the masking of a narrow band (sinusoidal) signal by a wideband noise source ... One can think of a critical band as a frequency selective "channel" of psychoacoustic processing; only noise falling within the critical bandwidth can contribute to the masking of a narrow band signal. The mammalian auditory system consists of a whole series of critical bands, each filtering out a specific portion of the audio spectrum. 4, record 4, English, - critical%20bandwidth

With the difference frequency between oscillators adjusted to zero with pure carrier gas flowing through the detector, the presence of a foreign vapor in the cell will produce a different frequency which is linearly related to the amount of material introduced through an injection port in the carrier gas stream and inversely proportional to the absolute temperature for a given component at a constant density or concentration in the cell and for a particular operating frequency. 2, record 5, English, - Clapp%20oscillator

Lock-in is a fundamental physical phenomenon associated with all oscillating devices. Laser gyros exibit the same phenomenon, in that the coupling mechanism is the reflection of light from one laser beam back along the path where it interacts with the oppositley traveling beam. This is called backscatter and is caused primarily by imperfect mirrors. Therefore, at low rotation rates, there is no frequency difference between the counter-rotating beams so that the gyroscope does not indicate any rotation. In spite of the ring laser gyro's dead zone whith lock-in thresholds on the order of hundreds of degrees per hour, it is still feasible to obtain measurements of rotation rates of less than 1 deg/h. 1, record 20, English, - ring%20laser%20gyro%27s%20dead%20zone

Record number: 42, Textual support number: 1 OBS
For static positioning, the reconstructed carrier phase is sampled at epochs determined by a clock in the receiver. The reconstructed carrier phase changes according to the continuously integrated Doppler shift of the incoming signal, biased by the integral of the frequency offset between the satellite and receiver reference oscillators. The reconstructed carrier phase can be related to the satellite-to-receiver range, once the initial range (or phase ambiguity) has been determined. A change in the satellite-to-receiver range of one wavelength of the GPS carrier (19 cm for L1) will result in a one-cycle change in the phase of the reconstructed carrier. 1, record 42, English, - reconstructed%20carrier%20phase

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead]. 2, record 45, English, - laser%20velocimeter
