I used to do this kind of stuff with imagemagick (Convert) long ago. the early 1980s brought all of the advantages of digital audio representation, including high fidelity, dynamic range, and robustness These advantages, however, came at the expense of high data rates Conventional CD and digital audio tape (DAT) systems are typically sampled at either 441 or 48 kHz using PCM with a 16-bit sample resolution This results in uncompressed data rates of 7056/768 Kbps for a monaural channel or 141/154 Mbps for a stereo pair at 441/48 kHz, respectively19 Compression techniques other than PCM are now also being sought for high-fidelity music Uniform Quantization In a basic PCM system, input to the quantizer hardware comes in the form of an analog voltage provided by the sampler circuit The simplest approach would be to use a uniform quantization method Here, the range of input voltages is divided into 2n segments, and a unique codeword of n bits is associated with each segment The width of each segment is known as the step size The range, R, of an n-bit quantizer with step size s is R (s)(2n) This implies that if the input voltage were to exceed R, clipping would result To address this issue, logarithmic quantization is used Logarithmic Quantization The goal of logarithmic quantization is to maintain a reasonably constant SNR over a wide range of analog amplitudes Using this technique, the SNR will not vary with incoming signal amplitude To accomplish this, quantize the log value of the signal instead of the incoming signal; for example, for analog values, w, the equation y h k log(w) with h and k constants provides such a logarithmic function21 Logarithmic quantization is a compression process: It reduces the dynamic range of a signal according to a logarithmic function After compression, a reverse process called exponentiation is required to recover a facsimile of the original; the entire cycle is often referred to as companding (for compressing/expanding)22 In North America, a specific logarithmic scheme called m-law is used; in Europe, a similar but not identical approach called A-law is used Both methods employ 8-bit logarithmic quantization with 16 regions and 16 steps per region Adaptive Quantization Speech signals contain a significant amount of redundant information By making use of this fact and by removing some of these redundancies through processing, you can produce data parameters describing the waveform with a lower data rate than otherwise possible and still be able to make a reasonably faithful reconstruction of the original Speech samples generated at the Nyquist rate are correlated from sample to sample (Actually, they remain moderately correlated over a number of consecutive samples) This implies that values of adjacent samples. how to create a thumbnail image of a pdf c#: Generate a pdf thumbnail (open source/free) - Stack Overflow create pdf thumbnail image c# How to Create Thumbnail Images in C# and VB.NET | DotNetCurry

The circuit diagram shown in Figure 9-2 illustrates the schematic for the 80/40 Meter Direct Conversion Receiver A dipole or suitable antenna is fed directly to input jack J1, which is coupled to potentiometer R1, which serves as a continuously variable RF attenuator and also serves as the receiver s gain control Using the RF gain control to set volume is advantageous as it also reduces strong in-band signals that could otherwise overload the receiver front end Series inductors L2 and L3, and trimmer capacitor C18, provide front-end bandpass filtering, and an impedance match to 50 to 75-ohm antenna systems IC U1 is an NE602/612 mixer and Local Oscillator (LO) in an 8-pin dip package The mixer section is an active Gilbert cell design for good conversion gain and low noise figure The LO section uses heavy capacitive loading to minimize frequency drift Tuning is capacitive, using a modern Hi-Q miniature plastic variable The local oscillator (LO) stability is enhanced by a 78L05 voltage regulator Since this is a direct conversion receiver, the LO is tuned to the carrier frequency of Single Sideband Signals, or to a difference of 300 to 800 Hz on CW . how to create a thumbnail image of a pdf c# Generate thumbnail image for office document in c# - MSDN - Microsoft
