Then if the input signal is a sine wave, an rc integrator will simply act as a simple low pass filter lpf with a cutoff or corner frequency that corresponds to the rc. The transfer characteristic of the circuit for increasingvi. We study the response of high pass rc and rl circuits to different types of inputs in the following sections. There are many cases in electronic circuits where signal or voltage waveforms other than sinusoidal ones are present. Wave shaping circuits electronic oscillator electromagnetism. O figure 1 a figure 1 b it steady state 4 transient. Module 8, introduction to amplifiers, covers amplifiers. The bistable circuit with the negative input terminal of the op amp disconnected from ground and connected to an input signal v. Perhaps the most widely used component of all circuits ib the rc circuit, consisting of a condenser in series with one or more resistors. Lessons in electric circuits, volume ii ac by tony r. It is quite evident why this type of rectifier is called halfwave. Electronic circuits linear wave shapping tutorialspoint. The wave forms associated with this circuit are shown in figure i b.
Applications of waveshaping clipping circuits based on zener diodes are of. The amount of distortion is determined by the rc time constant. They are frequency selective, so they can reduce the signal amplitude at some frequencies, without affecting others. The bistable circuit with the negative input terminal of the op amp disconnected from ground and connected to an input signalvi. Pdf applications of waveshaping clipping circuits based on zener diodes are of great interest in a wide range of modern electronic systems. Two important classes of circuits known as nonlinear wave shaping circuits. Module 9, introduction to wavegeneration and waveshaping circuits,discusses wave generation and waveshaping circuits.
Passive filters, often consisting of only two or three components, are used to reduce attenuate the amplitude of signals. Weve already seen an example of a clipper in the halfwave rectifier that circuit basically cut off everything at the reference level of zero and let only the positive. Linear wave shaping circuits the process by which the wave form of nonsinusoidal signal is altered by passing it through the linear network is called the linear wave shaping. High pass rc circuit is discussed part one contains sinusoidal input to rc circuit too. Testing and applications of nonlinear wave shaping circuits. The type of distortion is determined by the component the output is taken across.
Every wave has a certain shape when it is represented in a graph. An rc network can change the shape of complex waveforms so that the output barely resembles the input. Old company name in catalogs and other documents, april 1st, 2010. Similarly, if manual control of the delay is intended, then the voltage e may be derived. This shape can be of different types such as sinusoidal, square, triangular, etc. Pdf testing and applications of nonlinear wave shaping. Module 7, introduction to solidstate devices and power supplies,is similar to module 6, but it is in reference to solidstate devices.
