Basic Introduction to Filters

1.1 Filters and Signals: What Does a Filter Do? In circuit theory, a filter is an electrical network that alters the amplitude and/or phase characteristics of a signal with re-spect to frequency. Ideally, a filter will not add new frequen-cies to the input signal, nor will it change the component

Capacitors in loudspeakers explained -

In addition, the load will be given on the capacitor as a voltage rating. This indicates the amount of voltage a capacitor can be exposed to before it becomes damaged. Most manufacturers will use capacitors equipped to handle more volts than the system will typically give it. This is done to give the system a safety margin. For instance, if a

Active Components and Passive Components

Capacitors are passive components for storing or releasing supplied electrical power (electrical charge), by blocking DC while passing AC, in particular, passing high-frequency current very well. When DC is applied to a capacitor, it stores
