Essays on Reactance

Fear messages have been of importance within the nursing profession over the years and were even responsible for the reduction of the use of substance abuse in communities. Substances abuse is discouraged in many communities owing to their negative effects on the general health of an individual (DiBello, Neighbors, & Ammar, 2015). It is because of these adverse consequences that the nursing and health sector, in general, decided to come up with creative ideas to curb the menace. One of the commonly used strategies in this field is the formulation of fear messages to scare away the drug users from ...

I will analyse filters as a sub-set of the circuit. I choose filter because it is a core component of the audio equipment I have designed since it is responsible for ‘generating’ the high and low frequency signals that are fed to the tweeter and woofer respectively.

Filters

Unlike resistors, the opposition (or reactance) to current offered by capacitors and inductors vary with frequency. At lower frequencies, the reactance of inductors is low while that of capacitors is high. At high frequencies, the reverse happens and the reactance of inductors is high while that of capacitors is considerably reduced. Thus at very ...

Introduction

This report is about the design of a two-way crossover laud speakers. The major task is the building of the circuit diagram. In the design, I have ensured that the 12dB crossover follows the Linkwitz-Riley alignment. This is achieved through the use of a sub-Bessel filter whose Q is 0.5 instead of the common Butterworth alignment resulting from a Q of 0.707. At the crossover frequency, the Butterworth crossovers have a 3dB peak. This is the main problem of such crossovers. This problem occurs when the outputs are acoustically or electrically summed. With a filter whose Q is 0.5, the signal is ...
