Thank you NascentOxygen! You have been a great help =D I will just calculate the Voltage gain through hybrid parameter model in my report How do I calculate the corner frequency for the active low pass filter?

well i don't know Laplace but i know phasor analysis and complex numbers. I know how to convert that model into a hybrid parameter model and calculate the Av, Ai, Zi, Zo. looking at datasheets, the BC548 transistor hfe value has a min of 110 and max of 800. May I know what this means?

Square wave frequency The frequency of the square wave is 1 kHz. My apologies as i was not familiar with stage 1 earlier and hence I thought the input was a sinusoidal wave. See attached image ^^Question: 1. How do I calculate the theoretical output voltage for the sine wave? (Switch 4 from...

switch 4 switch 4 - sine wave

output waveforms hey guys! this is my output waveform for all 4 switches...switch 4 is in my post below...( cause i am only allowed to upload a max of 3 files only... ) switch 1 starts from the potential divider, then the first RC low pass filter..then another RC low pass filter and switch 4...

Well okay I did some research yesterday and found out that if I need a square wave generator I need to use VPULSE. Okay so I used that and instead of constructing the whole circuit, I constructed the circuit based on which switch I press on. I omitted the transistor because I didn't know...

Homework Statement Hi in response to my previous thread (principles behind the waveform selector circuit), I would now like to run a SPICE simulation using the PSPICE schematics software to obtain the theoretical values before entering my lab session. I have uploaded the schematic for your...

Thank you very much for your advice =D I will try to run the simulation with PSPICE...time to brush up my skills.

well our lecturer came up with this circuit as an introduction to our course which also forms our first project. I think the reason why he came up with this is because there is a section in our report where we have to point out the weaknesses of the circuits and suggest improvements to the...

The waveform is a sinusoidal wave The first stage is the testing of individual circuits so i tested by plugging in a (literal) signal generator and then selected the sine wave. I could then change waveforms by switching on different switches. Thanks.

Homework Statement Hi i have a practical project that i am working on. I am working on a waveform selector circuit. My circuit is part two of three circuits. The first circuit is a signal generator followed by the waveform selector and then a filter rectifier. I am required to produce a report...

THank you very much for your explanation! At first I didn't get it...then what I did was referring to your analogy of the spring-mass system, I drew a pictorial view of it and interpreted your explanation line by line until I fully understood everything. Thank you. That is what I needed. =D

Homework Statement I have a series LC circuit that consists of a 1V DC voltage supply, an inductor and a capacitor. The inductance of the inductor is 2mH and the capacitance of the capacitor is 1μF. I performed a transient analysis using a simulation software and I observed the trace of the...
