digital to analog converter 140 and finally to a filter 144 to remove any unwanted noise thus the output from filter 144 is delivered to the controller 68 in man machine interface 76 in general it should now be understood that the signal received at electrodes 92 96 and 100 is delivered in a substantially readable form from the output of filter 144 using the aforementioned components however it is to be understood that other sets of components that transmit over a wireless link such as link 88 are within the scope of the invention the format of link 88 is not particularly limited for example frequency shift keying u201c fsk u201d at about 433 mhz can be used to transmit the processed signal as another example presently more preferred signals are transmitted using amplitude shift keying u201c ask u201d in the about 902 928 mhz industrial scientific and medical u201c ism u201d band ask modulation is used to reduce and or minimize power consumption if the non digitized raw signals are needed they can be transmitted by changing a few components in the circuit and using frequency modulation fm transmission emg electrode signal channels are programmable 902 928 mhz and because of the bandwidth of the signals and the method of transmission transmission of multiple channels of emg data is possible thereby reducing the likelihood of interference from other sensors that may be nearby the 902 928 mhz band is presently preferred in which one can operate in north america however there are many cordless phones and other devices that operate in this band therefore to further reduce the likelihood of interference it can be desired to include further intelligence inside the sensor 84 and.
