Will a driver whose frequency dispersion effects begin at ~8,100 Hz be suitable for 20 kHz?
Will there be any dispersion problems with a speaker so small that it is a point source of sound?
No, 20 kHz is not suitable for a driver whose frequency dispersion effects begin at ~8100 Hz. As 20 kHz is larger than 8100 Hz frequency dispersion effect will be a major factor.
If the size of the speaker is considerable to a point source there will not be any dispersion problem unless the speaker is moving. A moving speaker is effected by the Doppler effects.

Design a high efficiency 3.3 V, 5A d.c.to d.c. power converter from a 4 to 5.5 Vdc source. The maximum allowable inductor current ripple and output voltage ripple are 0.1A and 20 mV, respectively. Assume a switching frequency of 20 kHz.a) Design a suitable converter power circuit using a MOSFET switch, showing all calculation of inductor and capacitor values and drawing a circuit diagram of the final design including component values. Indicate the peak inverse voltage and forward current rating...
question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...
Introduction: A manufacturing company that possesses many complexities can be highly challenged when maintaining production goals and standards in conjunction with a major organizational change. Garment manufacturing is a complex industry for many reasons. The product line is a complex array of styles, seasons, varying life cycles and multidimensional sizing. Many sewn product firms are viewing TQM as the appropriate strategy to meet the double demand of competition and quality; however, many companies are finding sustaining their TQM adoption decision...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...

Case Study 1: Should a Computer Grade Your Essays? Would you like your college essays graded by a computer? Well, you just might find that happening in your next course. In April 2013, EdX, a Harvard/MIT joint venture to develop massively open online courses (MOOCs), launched an essay-scoring program. Using arti ficial intelligence technology, essays and short answers are immediately scored and feedback tendered, allowing students to revise, resubmit, and improve their grade as many times as necessary. The non-profit...
