    square wave
    Charlie Hughes 05/16/13 04:56 PM,
    I’ve heard it argued by that square waves contain DC. How else could they have the flat top and bottom that make it square? Let’s look at a square wave and see what causes it to have its square shape. A complex waveform can be constructed from, or decomposed into, sine (and cosine) waves of various amplitude and phase relationships. This is the basis of Fourier analysis. A square wave consists of a fundamental sine wave (of the same frequency… View this post

    loudspeakers
    Pat Brown 05/14/13 03:06 PM,
    The procedure often followed for equalizing a loudspeaker is to place the measurement microphone on-axis and adjust for the flattest frequency response. This often involves boosting some filters when the axial response over a range of frequencies is lower than the average. Those that are opposed to the use of boost filters may choose to arrive at the same resultant response by reducing (cutting) parts of the response to the lowest common denominator. This results in the same electrical curve,… View this post

    amplifier damping
    Jerrold Stevens 05/13/13 02:21 PM,
    Ever have one of your friendly amplifier reps walk in your office to present their new mondo-gazillion-watt beast and point out the damping factor spec of greater than a bazillion? Why, gee-whiz! That’s like 10 times more than the other guy! It must be awesome! Right? Well, as we have seen before, it depends on how you are going to use it. Let’s start with defining damping factor and see what it means to us. Amplifier damping factor is defined… View this post
