class UnsignedTruncatedMultiplier(MultiplierCircuit):
&#34;&#34;&#34;Class representing unsigned truncated multiplier.
It represents an approximative version of unsigned array multiplier with simpler structure.
It is created by modifying an ordinary N-bit unsigned array multiplier by ignoring
(truncating) some of the partial products.
The design promises better area and power parameters in exchange for the loss of computation precision.

It represents an approximative version of signed array multiplier with simpler structure.
It is created by modifying an ordinary N-bit signed array multiplier by ignoring

The design promises better area and power parameters in exchange for the loss of computation precision.

Description of the __init__ method.
Args:
a (Bus): First input bus.
b (Bus): Second input bus.
truncation_cut (int, optional): Specifies truncation cut level used in the truncated multiplier circuit creation. Note: If equal to 0, the final circuit behaves as an ordinary array multiplier. Defaults to 0.
prefix (str, optional): Prefix name of unsigned truncated multiplier. Defaults to &#34;&#34;.
name (str, optional): Name of unsigned truncated multiplier. Defaults to &#34;u_tm&#34;.
&#34;&#34;&#34;
def __init__(self, a: Bus, b: Bus, truncation_cut: int = 0, prefix: str = &#34;&#34;, name: str = &#34;u_tm&#34;, **kwargs):
# NOTE: If truncation_cut is specified as 0 the final circuit is a simple array multiplier
self.truncation_cut = truncation_cut
