An auxiliary function built into the XR-2211, however, is tone detection to determine whether the modem is currently receiving a signal and that is the part used in Morse decoder circuit. The audio input signal
VK2IDL_CW_Decoder A Morse Code Decoder based on WB7FHC's Simple Morse Code Decoder. The CW decoder uses the same basic LM567 circuit designed by Budd Churchward WB7FHC which is connected to an Arduino Nano. I have made some software changes to suit my circumstances. These include a 'li...

some even giving me math discourses, correcting my R/C values. Please consider the op-amp filter circuit to be academic ONLY. The only reason for this project was to find a solution of the decoder, not the discriminator. The is not a product, just an...

All Morse Code keys work in a similar way to a push button or switch. They have two screw terminals, to which a positive and a negative wire are attached. When you press the key down, two bits of metal touch, causing a circuit to complete. The effect would be the same if you just...
FIG. 33 shows a portion of the electrical circuit functioning as a keyboard interface. Block U21 is a 4 line to 16 line decoder commercially available as component HC4514. FIG. 34 show the power supply in accordance with well known design techniques. Block VR2 is an adjustable voltage reg...

Alternatively, if the number of possible status conditions is relatively small, the code look-up logic 131 could be conveniently implemented by an arrangement of conventional ...
The circuit creates a partic. code which allows use of a logic process adapted to the partic. type of code, and uses a discriminating bit to create a series base code. The parallel transformation necessary to use an ASCJI code of the type is effected by a shift register whose outputs ...
The decoder automatically converts an analogue LF signal provided by a radio receiver into readable characters. It has an automatic level compensation device, a filter, an A/D converter and an interference suppression circuit. The filter can be tuned continuously to maintain a constant bandwidth of...
