The R C integration circuit is shown in Figure Z1605(a), and it is also one of the commonly used circuits in pulse technology. The time constant τ of this circuit is large, generally taking τ ≧ 10 tk .
When the input signal u i is as shown in Z1605(b), at time t 1 u o ( 
) = 0, after which u i charges C , u o rises exponentially; during t 2 ～ t 3, u i=0, capacitor C is in a discharge state, u o falls; during t 3 ～ t 4 , u o has exponentially increased, again and again, we get the output voltage of approximately sawtooth waveform, as shown in FIG Z1605 (c) are waveform u o.
The duty cycle of a rectangular pulse is different, and the amplitude of the output voltage is also different. Obviously, the larger the duty cycle, the closer the amplitude of the output voltage is to the amplitude E of the input signal.
Motion Control Sensor is an original part that converts the change of non-electricity (such as speed, pressure) into electric quantity. According to the converted non-electricity, it can be divided into pressure sensor, speed sensor, temperature sensor, etc. It is a measurement, control instrument and Parts and accessories of equipment.
