#Cliplets definition series

It may be observed that if it is desired to remove or clip the negative half -cycle of the input, the only thing is to be done is to reverse the polarities of the diode in the circuit shown in Fig 1 such a clipper is then called a series negative clipper SERIES-NEGATIVE CLIPPER WITH BIASДЇig 4 shows the circuit of a biased series negative diver. Therefore the diode is reverse biased and it acts as an open switch, Thus there is no voltage drop across the resistor during the negative half cycle as shown in the output waveform. During the negative half cycle of the input voltage, the terminal B is positive with respect to the terminal A.

Figure 3: Series Negative ClipperДuring the positive half cycle pf the voltage, the terminal A is positive with respect to the terminal B There for the diode is forward biased and it acts it as a closed switch As a result ,all the input voltage appears across the resistor as shown in Fig 3(b). In a series negative clipper a diode is connected in a direction appositive to that of a positive clipper Fig 3 shows the circuit of a negative clipper. The chipping level can be shifted up or down by varying the bias voltage (V B) It may be observed that the clipping takes place during the positive cycle only when the input voltage is greater thence battery voltage (i.e. Figure 2: Series Positive Clipper with Bias For this purpose a biased clipper is used Fig 2 shows the circuit of a biased series positive clipper. Sometimes it is desired to remove a Small portion of positive or apposite halt cycle of the signal voltage (input signal). Due to this reason the circuit is called series positive clipper. Hence the circuit of the Fig 2.1 is called a positive Clipper Here it may he noted the diode acts a series switch between the source and load. However a positive Clipper is that which removes or clips the positive half completely. All the input voltage is dropped across the resistor as shown in the output wave form.Д¬lippers prevent either or both polarities of a wave form exceeding a specific amplitude level. Thus there is on voltage drop across diode during the negative half cycle of the input voltage. Therefore it forward biases the diode and it acts as a closed switch. Figure 1: Series Positive ClipperДuring the negative half cycle of the input voltage the terminal B is positive with respect to A. This reverse biases the diode and it acts as an open switch Therefore all the applied voltage drops across the diode and none across the resistor As a result of this there is no output voltage during the positive half cycle of the input voltage. During the positive half of the input voltage, the terminal A is positive with respect to B. In a series positive clipper, a diode is connected in series with the output, as shown in Fig 1(a). Clipper Dual (combination)Diode clipper.The clipper circuits are of the following types. A clipper is a device which limits, remove or prevents some portion of the wave form (input signal voltage) above or below a certain level In other words the circuit which limits positive or negative amplitude ,or both is called chipping circuit.
