This voltage to frequency converter circuit use the CA3130 OP-Amp ICs, that linearity Of changing is very well up to 0.5% and Temperature coefficient of less than 0.01% per degree Celsius. In Figure 1, IC1 act as the frequency generator is controlled by voltage. Suppose, first the output voltage of IC1 is + 15V. C1 […]
Thanks for visiting our sites.

Sometimes we need to use a resistors that without capacitance or inductance. We always use the carbon resistors. But some working to need the resistor that has also many high power. Which we cannot use the carbon resistor because it has maximum power about 2 watts only. Normally, performance testing of amplifiers need to apply […]
The tremolo effect circuit widely used, making noise in the electronic music scene. The height of the modulation signal by low frequency between 1 Hz to 10 Hz. This result will sound good, When frequency be modulated in sine. Figure 1 Tremolo Effect Circuit using uA741 The circuit as Figure 1. Music signal is buffered […]
In the receiver, stereo radio station. Usually have more noise than listening in mono. Because, the stereo system is splits signals-to-noise ratio. (S/N) There level lower, cause interference, in mono with less. becausePhase noise of the 2-back phase. When combined into a mono signal was decreased by default. As principle the noise is high frequency, […]
There are many ways to build the dual power supply from a transformer that has one secondary coil.This good way as Figure 1 use two bridge diodes. The first section is normally working, others section (D1-D4) will work by AC signal from C1 and C2. To filter DC voltage of out others bridge diode of […]
