Frequency divider chain

Homemade antennas can significantly enhance the performance of AM and FM radios, short-wave receivers, and scanners. For enthusiasts of talk radio, experimenting with AM band antennas can lead to the ability to receive broadcasts from across the country with...

The 60MHz Frequency Meter/Counter measures frequencies from 10Hz to 60MHz with a resolution of 10Hz. This device serves as highly effective bench test equipment for testing and measuring the frequency of oscillators, transmitters, radio receivers, function generators, crystals, and...

The LM380 functions as an astable oscillator, with the frequency set by R2 and C2. By adding Q1 and driving its base, the output of an LM3900 is configured as a second astable oscillator. This setup gates the output...

This PIC software integrates frequency counter and frequency locking functions. By incorporating a couple of transistors and an operational amplifier (TL082), it is feasible to stabilize the LC oscillator frequency. The frequency reference is established from the measured frequency...

The output of the CA3179 is fed through the D1Q1 circuit. These components serve to boost the 1V output of the CA3179 to a standard TTL level. Depending on the position of range switch S2b, the signal is passed...

This document presents an intriguing collection of frequency dividers with division factors ranging from 2 to 10. All options are based on the 7490, which is a decade and binary counter. The frequency dividers utilizing the 7490 integrated circuit (IC)...
