How to make a high pass filter in PSpice?
The output plot in frequency domain or the bode plots of a simple high pass filter is given in the figure below, Lets’ design a simple circuit of a hgh pass filter. Open the PSPICE design manager on your PC by typing design manager in the search bar.
How to save half wave rectifiers in PSpice?
From the design manager click on the run schematic button to open a new blank schematic as shown in the figure below, After opening the new schematic before jumping into designing first save the schematic by clicking on the file button at the top left corner and then selecting save as so that we can access it anytime in the future.
Is the simulated circuit a low pass filter?
From the output it is obvious that the circuit simulated is a low pass filter. Above is shown the bode plot (frequency domain plot) of the circuit. At lower frequencies the circuit is allowing the voltage to pass through it and at higher frequencies it drops down to zero. Also the results are in accordance with the theoretical introduction.
How to simulate a circuit using PSpice step by step?
After that the circuits is simulated using PSPICE and you are provided with the step by step approach to simulate a circuit and the result are compared with the theoretical discussion provided (which should be same).
Is the high pass filter a first order circuit?
In the above circuit there is only one reactive component with resistor this shows the circuit is first order circuit. The response curves with respect to frequency and the capacitive reactance are given below: This response curve shows that the high pass filter is exactly opposite to the low pass filter.
Where to find the design manager in PSpice?
Open the PSPICE design manager on your PC by typing design manager in the search bar. From the design manager click on the run schematic button to open a new blank schematic as shown in the figure below,
How are filter behavioral models implemented in PSpice?
This application note shows how the filter behavioral models are developed and implemented using the Laplace function of PSpice, Given the filter bandwidth and order, the models simulate lowpass, highpass, bandpass, and band-reject filters. For ease of use, the models are developed as parameterized sub-circuits.
How are the transfer functions specified in PSpice?
The transfer functions are specified through .FUNC statements. The parameters a1 through a4 and b1 through b4 determine which filter sections of the model are selected by using a simple selection algorithm, based on the order of the filter specified by the user.
How are Param statements used in PSpice model?
Note that the PSpice function stp, which is used in the model, describes a step function where stp (x) is 1 if x>0 and is 0 otherwise. The α, ω, and Q values of the Butterworth response are defined as lookup tables using .PARAM statements. These values are looked up automatically given the order of the filter.
