In pulse code modulation, the analog message signal is first sampled, and then the amplitude of the sample is approximated to the nearest set of quantization level. This allows the representation of time and amplitude in a discrete manner. Thereby, generating a discrete signal.The following techniques can be used for Analog to Digital Conversion: a.

Quantization. Encoding. Low pass filter : The low pass filter …The key pulse takes on the current sampling instant to the amplitude value of the information. The PAM method is not normally used for direct signal transmission. It is an important precursor for the production of other types of pulse modulation, such as pulse code (PCM) - pulse duration (PDM) - and pulse phases (PPM) modulation.Types of modulation: 1.

Ltd. - Manufacturer,Supplier and Exporter of TDM Pulse Amplitude Modulation & Demodulation at reasonable prices.It cannot be 1 to 1 because 115200 bits per seconds is 14.0625 KBps (kilo byte per second), which is too slow. A UART simply encodes 1 as a high voltage level, and 0 as a low voltage level. For a 'normal' UART, baud == bit rate, so 115200 baud = 115200 bit rate = 11.520kBps (assuming 8N1 which means 8bits data + 1 start bit + 1 stop bit).Pulse Amplitude Modulation 4-level (PAM4) is a multilevel signal modulation format used to transmit signal.
