This is an upgrade from the first part in the sense that it can be adjusted to have more delay based inverters in the feedback (14). This Excel animation is pretty much the same as in the first model, a virtual joystick controls the number of stages in the ring by horizontal movement and it can also control the RC delay… Read More...

A Gated Ring Oscillator Demo – Part#1
An interactive animated demo of the gated ring oscillator in Excel 2003 based on the previous tutorial. This model stands out because of the real time schematic animation in Excel. It is controlled by a virtual joystick which is generated using a chart with a macro assigned to it. To start the model click the red dot within the joystick chart.… Read More...

How to Model a Frequency Modulated (FM) Signal – an insight
Both frequency and phase modulation are important not only in electronics but also in science and physics in general. It seems like a trivial chore but when I first tried to model such a signal some time back I hit a hard wall. Our minds easily understand kinematics concepts such as coordinate, speed, acceleration and the relations between them in… Read More... "How to Model a Frequency Modulated (FM) Signal – an insight"
