New and exotic destinations away from the hustle-bustle of touristy spots have emerged in recent years. They are holding out an irresistible appeal for an out-of-the-ordinary travel experience. A look at the best places in India for your year-end vacation. Tawang: Prayer Flags in the Clouds The picture-postcard beauty of this much-in-the-news hill station in [...]
COMMUNICATION IS THE KEY WORD
It is only logical that Education must enable an individual to become useful so that the family, community and the nation will benefit. Education should help to distinguish between right and wrong; and to arrive at correct decisions about the matter under discussion Achieving greatness or satisfaction in your career is not a fluent gun [...]
Designing of Electronics Attenuator
Circuit Diagram: Two low voltage, low power zeners are used to control electronically the level of an audio signal. The attenuation range is from 6 to 58dB for an input current from 0.042 to 77 mA corresponding to a control voltage from 2.7 to 7.5V. If control voltage is limited to 5V, the attenuation is [...]
Designing of Low pass filter – Subwoofer
The acoustic spectrum is extended by very low frequencies 20Iz and reaches as the 20000Iz in high frequencies. In the low frequencies is degraded the sense of direction. This reason us leads to the utilization speaker for the attribution of very low frequencies. The manufacture that to you we propose distinguishes these frequencies, in order [...]
Low impedance microphone amplifier
Description The circuit is a microphone amplifier for use with low impedance (~200 ohm) microphones. It will work with stabilized voltages between 6-30VDC. If you don’t build the impedance adapter part with T1, you get a micamp for higher impedance microphones. In this case, you should directly connect the signal to C7. Circuit diagram Layout [...]
Designing of Two way cross-over 3500 Hz
Cross-over they are netting usually with passive materials that have aim to separate a region of frequencies in smaller. Cross-over the manufacture that to you we offer it separates the acoustic region in two sub areas in order to we lead two loudspeakers for the high frequencies and for low. Cross-over they are essentially for [...]
