DCF77 to USB Converter


I like the handy DCF77 signal. In this project no clock should use it, instead the computers in my home network should be served by a precise time reference. Due to the fact most other interfaces are no longer available on modern computers, it uses the USB to forward the prepared DCF77 signal to the host.

Block diagram of FM transmitter and receiver and its explanation FM transmitter Frequency Modulation is the process in which the frequency of the carrier signal is varied by the modulating signal while the amplitude remains constant Using Reactance modulator direct method The FM transmitter has three basic sections. The exciter section contains the carrier oscillator, reactance modulator and the buffer amplifier. The frequency multiplier section, which features several frequency multipliers. The power output section, which includes a low- level power amplifier, the final power amplifier, and the impedance matching network to properly load the power section with the antenna impedance. The essential function of each circuit in the FM transmitter may be described as follows. The Exciter The function of the carrier oscillator is to generate a stable sine wave signal at the rest frequency, when no modulation is applied. It must be able to linearly change frequency when fully modulated, w
