Synchronous Serial Input EE6602 Notes

The sender along with the serial bits also sends the clock pulses SCLK (serial clock) to the receiver port pin. The port synchronizes the serial data input bits with clock bits. Each bit in each byte as well as each byte in synchronization

Synchronization means separation by a constant interval or phase difference. If clock period = T, then each byte at the port is received at input in period = 8T.

The bytes are received at constant rates. Each byte at input port separates by 8T and data transfer rate or the serial line bits is (1/T) bps. [1bps = 1 bit per s]

Serial data and clock pulse-inputs

On same input line − when clock pulses either encode or modulate serial data input bits suitably. Receiver detects the clock pulses and receives data bits after decoding or demodulating.

NOISE – EC6651 Notes:

Noise is an unwanted electrical signal which gets added on a transmitted signal when it is travelling towards the receiver. Electrical noise is defined as any undesired electrical energy.

For Example: In audio recording any unwanted electrical signals that fall within the audio frequency band of 0 khz to 15khz will interface with the music and therefore considered as noise.

Noise figure is a figure of merit and used to indicate how much the signal to noise ratio gets degraded as a signal passes through a series of circuits. Noise can be divided into two general categories:

(i) Correlated Noise : Implies a relationship between the signal and the noise.

(ii) Uncorrelated Noise : It is present all the time whether there is a signal or not. Uncorrelated Noise: Uncorrelated can be divided into two general categories:

(i) External noise and (ii) Internal noise.
