A two-input OR gate is designed for positive logic. However, it is operated with negative logic. The resulting logic operation will then be
A clock signal driving a 6-bit ring counter has a frequency of 1 MHz. How long is each timing bit high?
Assertion (A): In a serial in-serial out shift register, access is available only to the left most or right most flip flops
Reason (R): If the output of a shift register is feedback to serial input it can be used as a ring counter.
IC counters are
