Inside a Guitar Amplifier – Part. 1
In this article, we’ll break down a guitar amplifier into its functional parts and explain how each of these parts work. We’ll also look at how these parts interact with…
State Variable Filter
The state variable filter is a type of multiple-feedback filter circuit that can produce all three filter responses, Low Pass, High Pass and Band Pass simultaneously from the same single…
Passive High Pass Filter
A High Pass Filter is the exact opposite to the low pass filter circuit as the two components have been interchanged with the filters output signal now being taken from…
Passive Low Pass Filter
Passive filters are made up of passive components such as resistors, capacitors and inductors and have no amplifying elements (transistors, op-amps, etc) so have no signal gain, therefore their output…
