Department of Electrical Engineering, Southern Taiwan University of Science andTechnology,

Abstract. The paper presents the design and implementation of a wirelesselectric guitar with digitally integrated effector. Wireless audio modules arefirst employed that electric guitar players no longer to worry to stumble on thestage. Furthermore, in a traditional analog way, electric guitar players may facemany different kinds of effectors, such as distortion, flanger, and reverberation.It’s hard for players to control them by pedals. The digitally integrated effectorsare proposed and implemented by DE2-70 Multimedia Development Board.Finally, a little radio transmitter with multiple keys is equipped on the electricguitar such that the players can easily select the desired audio effect.
Keywords: Wireless Electric Guitar, Effectors, DE2-70.
1 Introduction
Compared to the classical guitar and acoustic guitar, electric guitar with powerfulsound attracts a lot of young music fans[1]. The reason why electric guitar can capturethe tone played is that the magnetic pickup installed in it. The people familiar with theelectric guitar often need to purchase many effects to make the sound effect morevivid. Fig. 1. shows some single electric guitar effects.
Fig. 1. Single electric guitar effects, Delay, Flanger, and Echo (left to right).
Due to the inconvenience of the single effect, there is the advent of integratedeffect, shown in Fig. 2. But it is bulky and must be controlled by pedal or button. Forthe guitar players, it is still not easy for them to do real-time manipulation. In thispaper, we hope to improve these missing by applying modern digital technology.

Fig. 2. Electric guitar analog integrated effects.
Currently, only few researches have been on this topic [2]. On the other hand, therehave been a lot of international researches on guitar effects [3-8]. This paper try to useAltera DE2-70 to finish wireless electric guitar with integrated digital effects.
2 System Description
The FPGA based digital integrated system will be first introduced. Then some topicssuch as wireless audio transmission, radio code transmission, and digitally integratedeffectors will be described in sub-sections.
2.1 FPGA Based Digital Integrated System
Fig. 3. shows the wireless electric guitar system blocks. The Altera DE2-70 board isused to finish to DSP (Digital Signal Procssing) , ADC and DAC functions.
Fig. 3. The wireless electric guitar system blocks.
2.2 Wireless Audio Transmission
To make the electric guitar wireless, we should elimate the wire from guitar tospeaker in the first step. In order to accelerate the realization of the creative concept inthis paper, we directly use a commercially available Waveconn 2.4GHz wirelessstereo headphone and modify it. Fig. 4 shows the 2.4GHz wireless audio transmitter.
Fig. 4. 2.4GHz wireless audio transmitter.
The corresponding and modified 2.4GHz wireless audio receiver is shown in Fig. 5.
Fig. 5. 2.4GHz wireless audio receiver.
Before the receiver in Fig. 5 is connected to the DE2-70, the proposed pre-amplifier and anti-aliasing filter circuit is required. It is worth mentioning that theoperating amplifier design uses single-power[10-11].
Fig. 6. Pre-Amplifier and Anti-aliasing filter circuit.
2.3 Radio Code Transmission
To save development time, the applied radio code transmitter and receiver in Fig. 7are also commercially available.
Fig. 7. Radio code transmitter and receiver (right and left).
2.4 Digitally Integrated Effectors
In the subsection, some effects in the proposed system are discussed.
2.4.1 Flange Effect
Flange effect is like Chorus, the difference is the delay for flange is about 0~35ms,while the delay for chorus is about 35~50ms. To combine both flange and chorus
effect, we try to finish the system difference equation in (1) and its schematic diagramis shown in Fig. 8.

Fig. 8. Block diagram of Flange effect.
2.4.2 Reverberation Effect
This effect is similar to echo effect. The filter in (2) can produce "one-fold echo" forthe given input signal. If the sample frequency fs is 16kHz, then the time differencebetween the input and the echo will be about 0.1 second.
]1600[*8.0][][ nxnxny (2)To produce a more realistic “multiple-fold” echo [13], (2) can be modified as (3).
The original FIR type in (2) becomes IIR type in (3).]1600[*8.0][][ nynxny (3)
The resulting Z transfer function is shown in (6), a so-called comb filter.

To make the reverberation effect more apparent in software simulation, the echoeffect in (2)-(4) is modified from 0.1second to 0.5 second and the feedback gain in(2)-(4) is modified from 0.8 to 0.6. A 0.6 second short music is used as input andthe resulting output is shown in Fig. 10 in Matlab simulation.

2.4.3 Distortion Effect
When a sinusoid signal is taken as input of a clipping circuit, a severe distortion willoccur and the resulting output is like a square wave. For auditory effect, it makes theoriginal soft sound become rude. This sound effect can be thought as the mostimportant one for some electric guitar palyers.
Before writing FPGA programs, the Matlab simulation can be applied to verify thedistortion function. Fig. 11(a) shows an input signal with hybrid frequency 100Hz and200Hz, Fig. 11(b) is the resulting output.

Fig. 12. shows the implementation of the wireless electric guitar with digitallyintegrated effector. In the electric guitar body, there are wireless audio transmitter andradio code transmitter. On the other hand, the FPGA DE2-70 is connected to wirelessaudio receiver and radio code receiver.

3 Conclusions
This paper has implemented a wireless electric guitar with digitally integratedeffectors. First, the wireless audio modules are employed to transmit electric guitarmusic. Secondly, the digitally integrated effectors is presented that electric guitarplayers don’t need to face messy wires and many different kinds of effectors, such asdistortion, flanger, and reverberation. The DE2-70 board is applied as the coreprocessor. Finally, to make the electric guitar players select the desired audio effect inan easier and quicker way, a small radio code transmitter with keypads is mounted onthe edge of electric guitar. Based on the proposed prototype system, the integrateddigital effector with more practical effectors will be investigated in the future.
