As is shown in the picture, the Pulse Demodulator is composed by CMOS Hex Inverter. This circuit can be used to process envelop detection on Amplitude Pulse.... -
In the figure is the 567 FM demodulator circuit. In the figure, the FM signal is input from 3-pin and the demodulated signal is output from 5-pin. The central frequency of the FM signal that the circuit can demodulate is: fo=1.1/RC. In the circuit, C1 is the.... -
As shown in Figure it is 567 FM demodulation circuit. In the figue, the FM signalenters from the 3 foot, the demodulated signal goes out from 5 foot. FM signal center frequency which the circuit can demodulateis: fo = 1.1 / RC, C1 isfilter capacitor, and C2.... -
PLL (Phase Locked Loop) can be used to make a FM demodulator. PLL circuit track the input frequency by controlling a voltage input of a VCO (Voltage-Controlled.... -
The FSK demodulator is the electronics device that converts the FSK signal to serial digital signal. To transmit digital serial data we use FSK modulation and.... -
Achieves high carrier and modulation suppression by using closely matched diodes and providing R1 for amplitude adjustment and coaxial line for phase adjustment. R2 provides slight amplitude adjustment. -W. H. Ellis, Diode Quad Modulator Suppresses Carrier.... -
Frequency-to-voltage converters form part of a wide variety of instrumentation circuits. They also find use in radio as FM demodulators. One interesting configuration for this application is the Diode Charge Pump circuit (DCP), which also doubles as an AM.... -
The advantage of synchronous reception of AM signals is widely known. It includes high selectivity, linearity of detection and a low noise level at the output compared to other ways of reception. The circuit diagram is shown in figure 1. The operation of the....

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.....
