A quarter wave antenna is an easy and good solution, but it is not small (433 MHz: 16.4 cm, 868 MHz: 8.2 cm) You can curl up such an antenna and make a helical antenna. This is often a good solution since it utilizes unused volume for a product. If you need long range and have limited space, then talk to an antenna expert !

Understanding PDM Digital Audio
PCM (Pulse Code Modulation): a system for representing a sampled signal as a series of multi-bit words. This is the technology used in audio CDs. PDM (Pulse Density Modulation): a system for representing a sampled signal as a stream of single bits. Sampling rate is the rate at which a signal is sampled to produce a discrete-time representation.

The statements have a free format and consist of fields separated by a blank. If one wants to continue a statement to the next line, one uses a + sign (continuation sign) at the beginning of the next line. Numbers can be integers, or floating points. For example, RES1 1 0 3500 or RES1 1 0 3.5E3 One can also use the following scale factors

fixed point format than ia, ib in input. AR1 point on cos. COS and SIN calculation are done by a single function for better optimization with Table Look-up and Linear Interpolation (Cf: application note Sine & Cosine on the TMS320C2xx ). Calculations are done with fixed point instruction to optimize the time calculation.
The Fundamentals of FFT-Based Signal Analysis and Measurement
Figure 1 shows the power spectrum result from a time-domain signal that consists of a 3 Vrms sine wave at 128 Hz, a 3 Vrms sine wave at 256 Hz, and a DC component of 2 VDC. A 3 Vrms sine wave has a peak voltage of 3.0 or about 4.2426 V. The power spectrum is computed from the basic FFT function. Refer to the Computations Using the

combination of simple sine waves with different frequencies, phases and amplitudes periodic composite signal (period=T, freq. = f 0=1/T) can be represented as a sum of simple sines and/or cosines known as Fourier series: f 0 is referred to as fundamental frequency integer multiples of f 0 are referred to as harmonics Composite Analog
CHAPTER 2 DIGITAL MODULATION 2.1 INTRODUCTION
vask (t) = amplitude-shift keying wave vm(t) = digital information (modulating) signal (volts) A/2 = unmodulated carrier amplitude (volts) ωc = analog carrier radian frequency (radians per second, 2 πfct) In Equation 2.12, the modulating signal [v m(t)] is a normalized binary waveform, where + 1 V = logic 1 and -1 V = logic 0.
Nature moves in the form of a sine wave, be it an ocean wave, earthquake, sonic boom, explosion, sound through air, or the natural frequency of a body in motion. Energy, vibrating particles and other invisible forces pervade our physical uni-verse. Even light part particle, part wave has a fundamen-tal frequency, which can be observed

spectral curves. This format is sometimes used to evaluate the integrity of the pulse. Ideally, the two curves should be approximately equal, as is the case in this example. Note that the input pulse was measured during a pyrotechnic development test. The pyrotechnic pulse in Figure 1 was measured during a nosecone fairing separation test
