4096 times the input frequency PWM clock signal, counts up (Q three ), until the base is full ICi-IC3 (sweet day), the output point d a MAX clock signal, which on the one hand

the voltage data loaded into IClr rIC3, leaving the other dare steady Ics flip, Q ugly, namely, the number is in the state count down, and then began to count down until the point a fork outputs a MIN the clock signal period, the signal voltage on the one hand the data reloaded ICi ~ ICz, on the one hand to the bistable flip IC5 original state, and counts up, and thereafter repeat the above process. voltage data values and subtraction of the pulse count port number is the same liquid on PWM demodulation, the smoothing filter Ri, Rz and cl, C2 turn into a DC voltage, high input impedance amplifier OP is also magnified by 2 times and then converted into o ~ + iov voltage.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
