Two low-cost integrated circuits can be combined to create a simple digital frequency meter. The combination of a frequency-to-voltage converter (FVC) and a dual-slope, analog-to-digital display converter (ADC) makes a small 2-chip frequency meter that can be run from one 9-volt battery...

...lines, AM or FM. transmitters). Typically, only two frequencies are transmitted. One corresponds to a logical "0, " the other to a logical "1. " A TC9400 V/F converter will. generate these two frequencies when connected as shown below. The potentiometer sets the V/F converter to the lower frequency...

...are electricity, water and gas. Water and Gas are measured with very similar systems while electric meters are very unique. Electric meters measure the power consumbed at a customers site. This type of meter is very easy to convert into an electronic version using an MCP3905 single-phase power...

...expires can be enabled by means of a function-register configuration bit. Multiclock Start-Up and Operation. It is also possible to switch to an internal oscillator frequency during start-up for a faster transition where necessary. PIC MCUs from Microchip Technology Inc. (Chandler, AZ) furnish... a suitable microcontroller for. 1 mVPP, which allows a bidirectional communication. bidirectional communications, remote passive keyless. distance of up to a few meters. See Table 1 for more. entry and low-frequency sensing applications. The. feature details. device includes a PIC16F636 microcontroller...

Make a high-accuracy frequency meter?
I was thinking of using a PIC 16F or 18F and making a high-accuracy frequency meter.

Surface-mount technology - Wikipedia, the free encyclopedia
fewer unwanted RF signal effects and better and more predictable high-frequency performance.

Subwoofer - Wikipedia, the free encyclopedia
The typical frequency range for a subwoofer is about 20?200 Hz for consumer products,[1 below 100 Hz for professional live sound,[2 and below 80 Hz
