1KHZ TEST TONE GENERATOR BLUETOOTH
When using this application with wireless communication such as Bluetooth or AirPlay, there may be cases that limitation of the playback frequency, lowering the output level and irregular noise, etc., may occur under the influence of wireless environment, communication equipment and communication state. The chirp signal is a sweep signal of extremely short duration, so it does not guarantee a playback frequency in the specified range. Please be careful that the high-frequency signals of high volume in continuous may damage the loudspeakers, even if your ears do not perceive it as being too loud. Frequency response measurement for Audio systems using White noise and Pink noise Testing and tuning for Audio amplifiers, Equalizers and many other Audio equipment. Burn-in for Audio equipment and Loudspeakers Testing for Loudspeakers and Headphones Preset frequency customization function. Frequency input by keyboard (in units of 0.1Hz). Frequency range of generated signal: 20Hz to less than 21kHz. (Octave band noise generation function: 1/1 or 1/3 octave band, burst playback function: ON/OFF cycle 1, 2, 5, 10 sec, or continuous playback) Noise signal generation (NOISE): white or pink noise signal. (Configurable frequency range: 100Hz - 16kHz, transition time: 0.1 - 1.0sec, start delay time: 3 - 10sec, Frequency variation curve: Linear/Exponential.) Chirp signal generation (CHIRP): Short-time sweep signal can be generated with linear or exponential frequency change. Sweep signal generation (SWEEP): sine wave frequency sweep signal. Sine wave generation (SINE): sine wave pure tone signal. This can be used for detailed analysis of a specific frequency band. In addition, the octave band noise generator allows you to generate 1/1 or 1/3 octave band noise. It can generate the reference audio signals such as sine waves, sweep signals, chirp signals, and noise signals (white noise, pink noise), and has a high precision of CD quality and a frequency accuracy of 0.1Hz.įor sweep and chirp signals, the frequency range and transition time can be specified by the user. This app can be used in a wide range of fields as a reference sound source for audio system testing, sound tuning, hearing testing and more. The tuning can be done by replacing (or adding) the capacitors with a voltage-dependent capacitor."Audio Tone Generator - ATG" is a powerful audio test reference signal generator app for iPhone. This way you can make oscillators on ICs well beyond 10 GHz. These are made by just cross-coupling a pair of transitors, and loading them with an LC tank. When it comes to on-chip oscillators, I think one of the most common oscillator architectures is the differential-LC-tank. These often offer high quality factors (which means low phase noise), but are impossible (or at least hard) to tune over a wide range. If you want a fixed frequency, you can use something like a dielectric resonator, crystal, or transmission line. The specifics depends on what your end-goal is. The standard 'microwave' architectures still apply: you have a resonant network (be it a crystal, LC tank, transmission line resonator, dielectric resonator, etc.) and you compensate for the loss inside that resonator with a negative resistance (using an active devices such as transistor or diodes). Conceptually, the way you generate a 10 GHz signal is the same as the way you generate a 1 GHz of 1 MHz signal - it's just that all the components become smaller.
