Block Diagram of Pulse Code Modulation Here is a block diagram of the steps which are included in PCM. In sampling, we are using a PAM sampler that is Pulse Amplitude Modulation Sampler which converts continuous amplitude signal into Discrete-time- continuous signal (PAM pulses). The basic blo...
The pulse position modulation block diagram is shown below which generates a PPM signal. We know that a pulse position modulation signal is easily generated by using a PWM signal. So, here at the o/p of the comparator, we have assumed that a PWM signal is generated already & now we have...

Variable rise and fall time pulse generators can be classified as either constant transition time or constant slope as a function of amplitude change. Unlike the con stant slope instruments, the Model 1915A provides the highly useful constant transition time. If the output pulse amplitude is to ...
Logical signal generatorsproduce logic pulses in the form of conventionalvoltagelevels. These generators are often called digital pattern generators. Pulse generators are able to generate pulses with variable delays and some even offer variable rise and fall times. It is used for functional validation ...
Block diagram of digital backpropagation. 5.2.1.3 Application of digital backpropagation-based DSP in optical transmission experiments Assuming the predictions of the “capacity crunch” mentioned in the Introduction [1] will indeed take place, an increase in the optical transport capacity is essential...
A boost converter circuit converts a DC voltage to another, typically higher, DC voltage by controlled chopping or switching of the source voltage. In this model, a MOSFET driven by a pulse-width modulation (PWM) signal is used for switching. A digital PID controller adjusts the PWM...
2. Description of the Prior Art In a pulse code modulation (PCM) system, a typical analog-to-digital encoder functions to quantize an analog sample and to generate a digital character. In nonuniform PCM encoding, for example, encoding according to a μ = 255 companding law such as is util...
