彩色电视接收机已从晶体管发展到了集成电路的阶段.电视机中除行输出等大功率器件外,中放、伴音、行帧扫描及彩色解调等部分均可由单块集成电路配合少量外接分立元件完成其功能. 集成电路按它的用途不同,可分为模拟集成电路及数字集成电路.数字集成电路的基本单元是各种逻辑门电路和触发器,主要应用在电子计算机等脉冲数字电路中.电视机的节目预选器及扫描电路中的数字同步电路要用数字集成电路构成.模拟集成电路又分为线性和非线性两种,线性模拟集成电路是指输出和
Color TV receiver has been developed from the transistor to the stage of integrated circuits.In addition to high-power TV output devices, the release, audio, line frame scanning and color demodulation and other parts can be a single integrated circuit with a small amount of external discrete Components to complete its function.Its integrated circuit according to its different purposes, can be divided into analog integrated circuits and digital integrated circuits.Digital integrated circuit is the basic unit of a variety of logic gates and flip-flops, mainly used in electronic computers and other pulse digital circuits TV program preselector and scan circuit digital synchronization circuit to use digital integrated circuits. Analog integrated circuit is divided into linear and nonlinear two, linear analog integrated circuit is the output and
