摘要： A pulse radar apparatus uses different frequencies, for example, frequencies one of which is a multiple or a submultiple of the other for a signal which becomes a reference of a control pulse for controlling a gate operation for a reception signal and a signal which becomes a base of generation of a transmission pulse. As a result, even if noise is caused by the gate operation, its influence can be removed in the processing of reception signals having different frequencies.

摘要： A picture signal transmitting system using a CATV network sends a picture signal from a transmission path to subscribers by using a radio transmitter and receiver, and in the picture signal transmitting system, there is no physical wire connection from a tap off of the transmission path to subscribers. The picture signal transmitting system using a CATV network includes a CATV center, a first radio transmitter and receiver connected to said CATV center through a CATV transmission path, and provided near a subscriber's house for concurrently sending out a side band signal obtained by up-converting a picture signal of a frequency bandwidth including a plurality of channels with a local oscillation signal of which level is larger than that of said side band signal, and the local oscillation signal, and a second radio transmitter and receiver provided in the subscriber's house for separately receiving the picture signal and the local oscillation signal sent out from the first radio transmitter and receiver, and down-converting the frequency bandwidth of the received picture signal with the received local oscillation signal to an intermediate frequency bandwidth.

摘要： The output of a voltage-controlled oscillator (VCO), after being passed through a resonator having a single-peak characteristic, is detected by a detector. The output of the detector is sampled and held at a time instant that the control input voltage to the VCO reaches a maximum and also at a time instant that it reaches a minimum, and the difference between them is fed back to the control input of the VCO. In this way, the center frequency of the VCO is controlled so that it becomes equal to the center frequency of the resonator. In the case of a VCO as an FM modulator in an FM-CW radar, the sample-and-hold timing is derived from a clock signal based on which a triangle wave is generated. In the case of a VCO as an FSK modulator, the sample-and-hold timing is obtained by detecting a 0 and a 1 in input data.
