摘要： A DMD (digital micromirror device) includes a substantially rectangular element face made up of plural mirror elements arranged in a matrix. The DMD is provided with a light shielding cover having a light transmitting portion which corresponds to the element face. Radiated from the illumination optical system including a rod integrator, the illumination light enters the element face, on a flat surface including the diagonal line of the element face, at an inclined angle with respect to the normal to the element face. Near a light exit face of the rod integrator, a mask plate is disposed to regulate a part of the illumination light. The mask plate has a mask aperture of substantially rhombus shape. The illumination light passing the mask aperture is reshaped so that an illumination area can be a substantially rectangular shape on the element face.

摘要： A digital signal processing device is disclosed. At an intermediate time point between respective sample data of a digital signal input is interpolated data expressed by the formula ##EQU1## wherein R.sub.l, m and n are positive integers. The digital signal interpolated with this interpolation data d is applied to a digital-to-analog converter where it is converted to an analog signal. This interpolation serves as a low-pass filter for removing unnecessary harmonic components, with the result that a analog filter used in a posterior stage after the digital-to-analog converter requires no steep characteristics and hence can be of a remarkedly simple structure and be manufactured at reduced cost.

摘要： The front end circuit is constituted by first and second signal paths for transmitting a high frequency signal received by an antenna, and a transfer switch for selecting either one of the signal paths depending upon the state of the received signal, and a circuit for converting the frequency of either one of the selected signals to an intermediate frequency signal. Two signal paths have different filtering attenuating and amplifying characteristics, thereby providing an optimum condition for either a local or distant reception of radio wave signals.
