摘要： In a receiver circuit, an analog signal processor frequency-converts an input high frequency signal into a baseband signal, and performs low pass filtering at a cutoff frequency below a desired-wave band. An ADC converts an output of the analog signal processor into a digital signal. A digital signal processor compensates an output of the ADC for a signal component in the desired-wave band which has been attenuated by the filtering operation of the analog signal processor.

摘要： In an interpolative modulator, a signal which varies by only .+-.1 with one clock from a 1-bit quantizer is used as a shift-direction control signal. The shift-direction control signal is given to a bidirectional shift register. The bidirectional shift register shifts data based on the value of the shift-direction control signal that has been received. The output from the bidirectional shift register is given as a control signal to a resistive-ladder-type D/A converter. The resistive-ladder-type D/A converter outputs an analog potential corresponding to a switch selected by the above control signal. Therefore, if a delay difference occurs between any two bits, two adjacent switches are simply selected simultaneously, so that the output from the resistive-ladder-type D/A converter varies continuously. Consequently, there can be provided an oversampling D/A converter of resistive-ladder type with high accuracy and an increased yield, which is free from glitch (transiently generated noise).
摘要翻译：在内插调制器中，使用从1比特量化器的一个时钟仅变化+/- 1的信号作为移位方向控制信号。移位方向控制信号被提供给双向移位寄存器。双向移位寄存器基于接收到的移位方向控制信号的值来移位数据。来自双向移位寄存器的输出作为电阻梯型D / A转换器的控制信号给出。电阻梯型D / A转换器输出与由上述控制信号选择的开关相对应的模拟电位。因此，如果任意两位之间发生延迟差，则两个相邻的开关被简单地同时选择，使得电阻梯型D / A转换器的输出连续变化。因此，可以提供具有高精度和增加的产量的电梯梯型的过采样D / A转换器，其没有毛刺（瞬时产生的噪声）。

摘要： An illuminator for a microscope contains a source of light and the microscope has a stage with an opening for upward passage of light from the light source to illuminate a specimen on the stage. The housing defines a window for passage of light from the source through the opening in the stage for illuminating the specimen. The housing also includes first and second support arms, and the housing is adjustable both horizontally and vertically, e.g. relative to the opening in the microscope stage.

摘要： A illuminator base for illumination of a microscope specimen from below the specimen includes a fluorescent lamp bulb for generation of illuminating light on a viewing axis. The fluorescent lamp bulb has at least two arms, each having an active volume within a glass wall. The arms are disposed with each active volume generally tangent to the viewing axis. A line intersecting the viewing axis and the axes of lamp arms lies at an acute angle to the viewing axis. Preferably the lamp bulb is u-shape, the angle is about 40.degree. and 50.degree., and light transmitted by the lamp arms along the viewing axis is substantially without shadow.
