1-03-1993 | It is often next to impossible to determine the acoustic behaviour of a home-built loudspeaker enclosure other than by ear. The meter desc...

1-02-1993 | When a variety of audio equipment (CD drive, D-A converter, CD player, DAT recorder) is connected together, jitter may often be present on...

1-01-1993 | Usually, the -3 dB (and -20 dB) roll-off points on the frequency characteristic of a filter are found with the aid of an oscilloscope or a...

1-12-1992 | The demodulator ts based on a Type TDA8341 chip, which is the successor of the weIl-known Types TDA2541 and TDA3541. Apart from a demodulato...

1-12-1992 | One way of desigining a low-noise amplifier is the shunting of several input stages. This reduces the overall noise, Un=U(i)n-1/2, where...

1-12-1992 | Modern TV tuners normally contain means to scale down the VCO [voltage-controlled oscillator) signal. The one used in the proposed synthe...

1-12-1992 | The data generator offers a simple means of testing a circuit.There is no need of software for some microprocessor and all the components...

1-12-1992 | This little circuit converts temperature measured by an NTC (negative temperature co-efflcient) resistor inta a digital signal. The resis...

1-12-1992 | Opamp TypeSSM2017 from PMl is eminently suitable for designing a very-Iow-noise microphone preamplifier.

1-12-1992 | One advantage bipolar opamps have over FET types is that their input noise level is appreciably lower. However, when abipolar opamp is us...
