    摘要: An image forming apparatus forms a patch image on a recording medium, irradiates the patch image formed on the recording medium with light, and detects a quantity of light reflected by the patch image and outputs a first detection signal. The apparatus detects a quantity of light emitted by a light emission source and outputs a second detection signal, and amplifies the first detection signal in accordance with a first amplification gain and outputs a first amplified signal. The apparatus amplifies the second detection signal in accordance with a second amplification gain and outputs a second amplified signal, and controls image forming conditions based on the first amplified signal or the second amplified signal. An adjustment mode is executed prior to controlling the image forming conditions, and the first amplification gain is controlled when the patch image is formed with black toner, and the second amplification gain is controlled when the patch image is formed with color toner.

    摘要: A wideband receiver (10) comprises a frequency converter (16) for converting the frequency of a signal inputted through an antenna (12) by using a local oscillation signal from a local oscillator (18); a wideband filter (20) for receiving the output of the frequency converter (16) and passing a signal component corresponding to the scanning band including the bands of channels; an A/D converter (22) for converting the output of the wideband filter (20) into a digital signal; an FFT operational circuit (24) for receiving the digital signal and subjecting it to high-speed Fourier transformation; and a control circuit (26) for detecting the channel in communication in a predetermined scanning band on the basis of the results of operation of the FFT operational circuit. The control circuit (26) repeats the change of the scanning band by changing the frequency of the local oscillation signal, to detect the channel in communication with an assigned frequency range, i.e., a search frequency range.
