Digital Frequency Generator

Digital Frequency GeneratorMost of the modern low-frequency generators are used for testing, repairing and checking electric equipment. Modern generators can make adjustments in analog and digital amplifiers using various methods. They can also be used for such difficult tasks as adjusting amplifying and radio frequency channels in radios and TV sets. In order to get inside a generator and learn about its qualities and abilities we don't have to break expensive equipment. It is not designed for these purposes. You can simply try building something similar. For instance, you can assemble a simple digital generator. It consists of a limited number of inexpensive components.The following components have been used:1. A small segment of a circuit board.............2. Two microcircuits K561LA7, a microcircuit from the KMOP series, and a 561 IE16, a 14 discharge counter including output buffer amplifiers for each division circuit..........3. A clock quartz with the frequency of 32768 Hz......4. Three capacitors and one resistor for 5.1 megaohms.....Additionally the generator has a discrete switch. It also serves as a visual aid. The switch is used for output of the generated audible frequency. There is also a simple capsule for producing sounds.The device uses a stabilised power supply at 3 to 9 V. The current consumption is almost zero. In this case I'm using two 1.5 V batteries. I can't find anything more stabilised......In the end let's test different frequencies produced by the generator. We'll use a multimeter in the frequency measuring mode.....The measured value is within the range of 2 to 32768 Hz.

How do you talk but make your lips move differently. Very clever.

@prence1725 well frequency generators are widely used in the field of telecommunication

[prence1725]

what is the uses of this?
