The MAX481E, MAX483E, MAX485E, MAX487E–MAX491E,
and MAX1487E are low-power transceivers for RS-485 and
RS-422 communications in harsh environments. Each driver
output and receiver input is protected against ±15kV electrostatic
discharge (ESD) shocks, without latchup. These parts
contain one driver and one receiver. The MAX483E,
MAX487E, MAX488E, and MAX489E feature reduced slewrate
drivers that minimize EMI and reduce reflections caused
by improperly terminated cables, thus allowing error-free
data transmission up to 250kbps. The driver slew rates of the
MAX481E, MAX485E, MAX490E, MAX491E, and MAX1487E
are not limited, allowing them to transmit up to 2.5Mbps.

simulating a convolutional encoder
allows the user to input a source code to be encoded and also input the values of the generator polynomials. It outputs the encoded data bits, where 1/n is the code rate
Produce Java classes to calculate and display the root of a quadratic equation when input the coefficients a, b and c within the range of -100 to 100 by user.
To find and output 11-999 between the number of m, it is to meet m, m2 and m3 are several palindrome. The so-called palindrome refers to the number of its symmetrical figures that the whole number, for example, 121,676,94249 and so on. To meet the above requirements, such as the number of m = 11, m2 = 121, m3 = 1331 palindrome are few. Please prepare function int svalue (long m) to achieve this function, if it is palindrome, is a function to return, while return 0.
