摘要:
A digital filter having a small amount of hardware is realized by constructing a cosine roll-off filter. In the filter the first and fifth multipliers and the second to fourth multipliers are respectively shared. Three selectors are provided corresponding to the multipliers, and coefficient groups ka1 to ka3, and kb1 and kb3 are inputted by the selectors to the corresponding multipliers by time sharing. The results of multiplications by the multipliers when the coefficient groups kb1 to kb3 are inputted, are added between corresponding multipliers by adders. A final output is derived from an output selector.

Rotational force of a driving motor is transferred to a photosensitive drum via a planetary-roller reduction device, so that the photosensitive drum is rotated. A speed detector set on the shaft of the photosensitive drum detects the rotational speed of the photosensitive drum. In accordance with the detected rotational speed of the photosensitive drum, the rotational speed of the driving motor is adjusted so that the photosensitive drum is rotated at a constant speed.

摘要:
An interference compensator for compensating interference waves with long delay times generated during digital microwave communications system-based relaying of waves at a single frequency. The compensator receives a demodulated digital signal, passes the signal through shift registers with different delay times, and then, through a forward equalizer, a first backward equalizer, a second backward equalizer and a center equalizer. All equalizers are transversal type equalizers, outputs from which are added as an output. In addition, the compensator is equipped with a delay time control circuit which monitors the tap coefficients of the forward equalizer, the backward equalizers and the center equalizer and controls the delay times of the shift registers so that the tap coefficients become greatest at the center delay circuits of the respective transversal type filters.

摘要:
A sensing unit is constructed of a heater element and a temperature sensing element. The sensing unit is arranged in a region, in which measurement air, which flows into the inflow passage through the bypass inlet, bends at the substantially right-angle and contracts in flow. Alternatively, the sensing unit is arranged in a region immediately after an area, in which the measurement air flowing through the bypass inlet bends at the substantially right-angle. The lengthwise directions of the heater element and the temperature sensing element are respectively arranged to be in parallel with both thickness-wise side faces of the measurement body. Thereby, even when a flow rate of measurement air changes, an influence due to the change can be restricted from being exerted. Therefore, the maximum flow rate can be measured within the lengthwise range of the heater element from a low flow rate to a high flow rate.
