Continue ReadingWhat you should know: In the previous lesson we saw that every bit in a binary number has a value that can be calculated using the following rules: Bit Value 0 The value is always 0 1 , where position starts from 0 at the rightmost part of the sequence and increases moving to the […]
Continue ReadingWhat you should know: In the previous lesson, we were talking about the behavior of sequences of several bits. We showed that we were able to double the number of combinations that could be attained, just adding a bit to the left and repeating the same sequence twice, where the leftmost bit changes from 0 […]
Continue ReadingThe Bode canonical form is a widely used representation of the transfer function. One of the main reasons is that, using the parameters contained in the formula, drawing a graphical representation of the transfer function, in the frequency domain, becomes particularly easy. The parameters that appear in the formula have a physical meaning that can […]
Continue ReadingThis article refers to the analysis of a simple low pass filter. The circuit is made of a resistor and capacitor, connected in series. In order to keep things simple, the calculations will be carried out in the Laplace domain. Using the voltage divider formula, we can write: If the formula is simplified and […]
Continue ReadingThis article deals with a simple differentiator circuit, using an operational amplifier. If we use the generic formula of the transfer function of a generic operational inverting amplifier, we can write: Where is the feedback impedance, while is the impedance connected to the input. The transfer function has just one zero in the origin […]
Continue ReadingIn this article, a resonant RLC circuit will be analyzed. This circuit contains a capacitor and an inductor that continuously exchange their energy with one another. As a result this kind of device can manifest an oscillator behaviour and its transfer function includes a second order factor in the denominator. Another interesting feature of this […]
Continue ReadingIn this article, we will deal with a simple high pass filter, made using a capacitor and a resistor, connected in series. We already saw something similar in the article about a RC circuit, but this time the output voltage will be measured on the resistor instead of the capacitor. Obviously the circuit will behave […]
Continue ReadingWordPress is a very popular content management software, because it allows anyone to build a website, even without any knowledge about HTML or programming. This tutorial should work on several Debian based Linux versions, and has been specifically tested on Ubuntu and Raspberry running the Raspbian operating system. Apache installation The engine running at the […]
Continue ReadingComputers represent and memorize data using electronic components that can assume only two states: on or off, just like a switch. The information that can be stored in a switch is the simplest that can be stored in a computer system and is called a bit. This means that every kind of information that we […]
